On kibble, cancer & all the nonsense in between

“I thought you were a better dog mum…” somebody told me the other day after I mentioned kibble as a part of my boys’ diet. Agreeably, my parenting skills may be subjective for all parents are unique. On the other hand, my knowledge of food and it’s properties for human and dog health does come with diplomas, certificates and tax return forms confirming that I studied and practised in the field of human and pet nutrition for almost 20 years now.

And yes, my dogs do eat kibble. It has been on a menu since they were conceived. And it will remain on the menu because they’ll tell me off if it’s gone.

They love it. They look fabulous on it (in fact, it was their good looks that made “the better dog parent” ask me about their food). And they are healthy and active. That’s good enough to me.

I admit, I spent a lot of time choosing their food. It’s never complicated and far from fancy, but everything that goes into their mouth comes from the brands I trust and is made with ingredients that don’t put me into a freezing state of anxiety.

Today I wanted to talk to you about it because I often feel that many pup parents also experience anxiety, fear and borderline paranoia when it comes to choosing food for their spaniels, especially if the puppy eats kibble. 

How did kibble as such come about?

For centuries domestic dogs ate the same cooked meals and foods as their families. In 1860 James Spratt introduced the first commercially-made dog biscuits made from beef blood, wheat and vegetables. The “Meet Fibrine Dog Cake” was expensive but proved to be so popular among British gentleman and their sporting dogs that the company became the largest pet food manufacturer in the world.

It was the matter of convenience and dogs obviously enjoyed what they were given even though the original recipe wasn’t perfect. When it comes to the English cockers, many were fed a mixture of dry biscuits and cooked food with the most prominent breeders singing praises to a pressure cooker as “one of the greatest inventions”. Later on many moved onto commercial dog food.

What are the benefits of kibble?

A good quality complete formula provides all nutrients a dog needs to be fit and healthy. It takes away any guess work for all pup parents because one really does need to be a trained small animal nutritionist to create a balanced home-made diet on a daily basis.

It is an affordable option. You can buy good quality dry food without spending a fortune. This helps many dog families to feed a dog well on a certain budget.

Dry food keeps well and makes a useful backup in many situations whether you are at home, unwell and cannot go to the shops, or travel and need to have a supply of food that won’t go off.

Some formulas may have a positive effect on plaque control (1, 2, 3, 4)

Veterinary foods can literally save your dog’s life, help with severe allergies and dermatological conditions, and the easiest and scientifically-backed option during recovery, chronic illness or while a pooch is trying to lose weight.

Can kibble really kill our dogs?

Kibble does not kill dogs. In fact, any kibble from a PFMA-registered manufacturer will always be a better option than a typical home-made or raw diet that are practically never balanced and may even contain heavy metals above any reasonable limits. There have been studies and reports on cockers who survived DCM after their diet was swapped from home-made food to commercial kibble, and other case studies of puppies suffering from malnutrition and bone abnormalities after eating raw-based diets.

It is true that kibble may contain aflatoxins because these substances are present around in abundance. They may be found in grains due to poor storage, changes in moisture and temperatures, or when crops survive extreme weather conditions or insect damage. However, any responsible pet food manufacturer abides to a set of very strict rules and practices including pet food safety and regular testing of their ingredients before they leave the supplier or upon delivery of each batch. The storage practices are also regulated.

Pet food companies get their supplies of grains from the same sources as human food companies, so if you believe that your dog’s kibble may contain mycotoxins and thus be harmful, you must also admit to yourself that any rice, oats or barley you cook for your family is also a source of danger.

It is true that there were food recalls of several brands due to aflatoxin poisoning in dogs. They happened in the US, 12 episodes were documented between 1975 and 2006, the ingredient in question was corn, not rice, wheat or barley, on two occasions the harm was caused by too much vitamin D3 or synthetic antioxidants. For the 2006 case it was established that the manufacturer “did not adhere to its own stringent guidelines for aflatoxin testing of 12 shipments… The final food product was shipped to… retailers in 23 states and at least 29 countries.”

These cases are rare, very rare and so far seemed to occur in the States and Australia, not the UK or Europe, and always – due to malpractices and carelessness. Your dog is more likely to catch bacteria from a raw food or suffer from malnutrition if he eats home-made diet than get poisoning from commercial kibble.

The 2007 melamine poisoning that was an absolute tragedy for many families also happened in the US because the company used ingredients containing melamine.

And in 2018, 2019 and 2021 several brands of dog food had to be recalled because they contained too much vitamin D. If it makes you feel any better, it is more likely that food recalls would involve human food, especially in its natural, raw state, than pet food. And it’s worth to mention that raw pet food also gets recalled too, though manufacturers do not always make it known to general public and the updates end up on food safety news website only. There were 51 samples of raw food (three quarters of all tested) that failed safety tests in the EU due to bacterial contamination in 2019, was a raw food recall in the UK and 67 (yes, 67!) cases in the US in 2020 and 2021.

So it’s not all black and white and all we can do is to choose manufacturers we trust among the ones registered with PFMA and keep on living. No company wants to recall their food or intentionally cause harm to our dogs. Yes, ALL companies are interested in making profits because it’s the nature of any successful business. But any successful business also exists because of their happy customers, so they will always do their absolute best to keep things safe. My dogs eat food made by British company who use a mixture of regular and organic ingredients that they farm (except the rice) making it fully traceable, use no preservatives or synthetic additives and BPA-free packaging.

Does kibble cause cancer?

I would not let you go unless we talked about the big C vs big K (for kibble) question. Canine cancer is a complex subject. It goes far beyond the subject of nutrition even though nutrition does play a very important role. The frustrating part is that dry food got the blame for everything because of some studies that got taken out of content and re-told in ways that suited the story tellers and their personal objectives and believes – not the unbiased views of knowledge or science. If you look closely, the tales often originate on blogs and websites of people who may look for somebody to blame or use it as a marketing strategy to divert people attention from “killer kibble” to their own brand of food or product.

First of all, the kibble is directly and conveniently compared to human junk food because this is a kind of association many could easily understand – not because the two are alike. Any junk food or many processed foods you’d get in certain food chains really are garbage however you look at them. They are completely unbalanced nutritionally, made with a few ingredients that have once been natural (do you get a piece of mind being assured that a milk shake does contain milk? because it has to be specified to be believed?) and then enhanced with sugar, preservatives, additives, colorants and flavour enhancers before being dipped in hydrogenated fats. Naturally, nobody, absolutely nobody, would remain healthy if they regularly ate these “foods”.

On the other hand, good quality kibble is made with ingredients and animal parts that came from the same factory as human foods. The only difference is that the dogs are given parts most humans would  find unappetising (unless some junk food chain mashes them into a pulp and uses this mince to create objects that resemble chicken breast or real burgers). Pet food companies that follow strict standards will never use road kill, dead animals or put hairs, hooves, horns and other inedible parts into their products. This is against the law. On the other hand, bird feathers and human hair can be legally used in some flours and breads made for human consumption, and beaver anal and urine secretion may end up as a natural flavouring in your strawberry ice-cream. 

The temperatures used to make extruded kibble were initially around or over 200C. These days many companies produce kibble at temperatures of 120-180C. Some go even below 120C. A few use cold pressed method. Yes, using any form of heat can reduce certain nutrients, but it can also destroy harmful bacteria and anti-nutrients that can affect dog’s health. Also, if you just think about it, every time you cook anything in the oven for your own dinner, the temperatures would be around 165-200C, but it won’t necessarily mean that all those meals will lead to fatal disease, just like eating raw diet 100% would not necessarily turn you into a picture of health or give you a supermodel physique.

The carbohydrates in kibble are not necessarily the cause of cancer either. Yes, sugar, particularly refined sugar, may be responsible for inflammation and cell mutations. On the other hand wholegrains, starchy vegetables and fruits contain various forms of sugars, but they also contain fiber that helps to reduce the risk of digestive issues, and vitamins and minerals that work as antioxidants protecting the body and keeping it strong and potentially cancer-free. And I just have to mention that barbecuing your favourite steak or cooking any meat to achieve that tempting brown crust also causes production of acrylamides as well as other carcinogen (especially true for the BBQ)

You might have also heard of acrylamides as one of the reasons to avoid kibble because these substances are formed in many foods as as a result of cooking at high temperatures, which is known as Maillard reaction. So far all is true. It is also true that acrylamide in its various forms is concidered to be a potential carcinogen for humans because it caused tumours in rats that were given experimental oral doses of acrylamides as a part of a study. However, according to science, we cannot really be fully compared to rodents because humans aren’t rats, one has to be extensively exposed to acrylamide to be at risk through either industrial exposure or smoking, and there was no exact link between breast cancer and acrylamides in US women. When studies looked into dietary sources of acrylamide, the outcomes were inconclusive for several reasons: the amount of acrylamide varied greatly between foods, many “healthy foods” contained acrylamides yet were fantastic sources of nutrients and cancer-fighting antioxidants, and Maillard reaction could include production of other substances, not just acrylamide. It has also been established that boiling and cooking on a hob at lower temperatures did not produce acrylamide. But over-baking, frying, deep-frying and microwaving did. Additionally, the list of worst foods included crisps, chips (half of the total exposure!) and bread – all of them are sources of either white potatoes or refined flours, not vegetables of wholegrains!

When it comes to pet foods, a small study did find acrylamide in certain brands of pet food. The selected formulas of kibble were based on derivatives and unnamed grains and thus can only be viewed as an example and not the indefinite proof. However, even this small research mentioned that the amount of acrylamides were “relatively moderate compared to human food” and several other studies demonstrated that acrylamide can be metabolised and detoxified.

Another study included three lab puppies that were fed burnt maize porridge by their breeder and died. Acrylamide was considered because the porridge was badly burnt and there were no bacterial or other infections found in pups through testing. However, the researchers only suggested acrylamide as a possible reason. It was also mentioned that the puppies have not been fully vaccinated and when they were operated on, the vets also found hard objects in their stomach, which turned out to be the undigested porridge, so it could also contribute to the tragic outcome.

Regardless of what you do, our exposure to acrylamide is unavoidable. We can potentially reduce the risk of over-exposure, but all living creatures will still end up with some of those molecules in their bodies for about 24 hours and then detoxify most of the substance provided the body, and the liver in particular, are healthy.

It is also incredibly important to remember that dogs are much closer to humans in their biology and reaction to disease than rodents, so chances are, dogs reaction to acrylamides will be similar to ours, not the ones of lab rats. When beagles were given very high doses of acrylamide in 1974, they developed neurological symptoms. A 1981 study on greyhounds reported that dogs suffered from nerve damage and difficulty swallowing after they were given pure acrylamide in a water solution. A 1984 study also showed that dogs absorbed the substance rapidly, but over 60% was later excreted naturally. In all three cases, however, the exposure was extensive and affected the nervous system, but did not cause cancer. 

Disease, neither human nor canine, is never limited to temperatures. Never. It is a combination of genetics, breed predisposition, health status, preventative and medical care, weight, lifestyle, emotions, choice of every product you’d have around your home (and choice of home and homewares too!), choice of tableware and cooking utensils, choice of ingredients and storage, activities and rest, places you visit and locations you avoid.

Saying that kibble is cancerous simply because it is processed at high temperatures is wrong and misleading. It instils fear, and fear leads to serious mistakes and can even puts you and your dog in a state of disease.

Cancer can happen to dogs and people who have been eating healthy food and living a healthy life and it may never happen to people or dogs who existed on very poor quality diet, smoked, drunk and moulded the sofa to replicate the shape of their derrier.

Dry dog is not evil and is definitely less problematic than anything you’d whisk yourself on a whim or feed your dog any commercial foods that are based on trends more than science. 

Use a trusted PFMA-registered manufacturer, consult a qualified nutritionist about creating a balance between your dog’s main diet and a few fresh and healthy treats, test your dogs vitals once a year if veterinary assessment alone does not give you a full peace of mind, use preventatives, groom well, stay active, create a dog-friendly home free from products and substances that can harm your cocker. 

Toxic ingredient substance in grapes that causes poisoning and kidney damage in dogs / grapes, raisins and sultanas toxic to dogs / nutrition for cocker spaniels / canine nutritionist UK / pet nutrition coach online / Perfect cocker spaniel: dog blog, book, spaniel grouping, puppy tips, diet information articles (C) Natalia Ashton

This substance in grapes may be the cause of poisoning – and found in your pantry too

Grapes are toxic to dogs. It’s the fact that most dog parents know about. The fruit is so dangerous for the pooches that eating grapes (19.6g per 1kg body weight), raisins or sultanas (2.8g per 1kg body weight) can damage the kidneys and be potentially fatal.

The exact mechanism of poisoning is still unknown and so far it has been linked to mycotoxins, heavy metals, pesticides, excessive amount of glucose in grapes, and even vitamin D.

And now there have been a breakthrough that may actually explain the cause of the problem.

According to a letter published in the April 2021 issue of Journal of the American Veterinary Medical Association, the dogs may be reacting to tartaric acid also known as potassium hydrogen tartrate. The lightbulb moment happened when a dog ate some home-made play dough containing cream of tartar (a common pantry ingredient obtained as a byproduct of wine making and used as a baking ingredient) and developed symptoms similar to the ones caused by grapes.

The group of veterinarians who dealt with the poorly dog and  analysed the ingredients of his eaten “trophy”, reported the link to the JAVMA adding that grapes are one of the unique fruits (tamarind is the other one to think of) with high quantities of tartaric acid / potassium bitartrate – the substances that have been known to cause sensitivity reaction and poisoning in dogs in the past.

More research will be needed to confirm this theory. Until then, keep your dog away from grapes and remember to check dog treats and recipes for the cream of tartar because it is often used as a raising agent and flavour enhancer in dog biscuits. And if you love your Palvolva, you’d often use cream of tartar to achieve extra fluffy meringue and super voluminous whipped cream, so remember to never let your dog pinch those either.

Can dogs eat pears?

Can my dog eat… pears?

Carrots, apples, blueberries… more often than not these fruits are on top of the snack list for most canines. But what about pears? I have recently got into the habit of giving my boys a small slice of pear every morning, and the pups seem to love it so much, they give me a look of betrayal if I forget about the treat.

I’ve always knew that pears (but not the seeds) can technically be given to dogs, yet I have hardly seen anyone feeding the fruit to their cockers. Sounds odd, doesn’t it?

And if you like pears as much as I do – and clearly as much as Coop and Fred do – sooner or later you’ll end up asking yourself…

CAN OUR DOGS EAT PEARS?

YES! They absolutely can!

Pears can be such a wonderful addition to the menu if your spaniel enjoys the taste. First of all, pears are a source of fibre, quite a bit of fibre, actually. A human serving of fruit provides 6g of it. And the fibre will keep your dog’s digestive system functioning, help to clear out the toxins, maintain healthy anal glands and may even reduce the risk of some cancers. According to animal studies, eating pears also reduced formation of ulcers in the gut.

In addition, pears are full of water to maintain hydration.

Nutrient-wise, the fruit is known as a source of vitamins C and K, and minerals potassium and copper. Thus eating pears may support the immune system, blood clotting, healthy heart and blood pressure, haemoglobin levels, maintenance and production of collagen and elastin for healthy skin and tissues, and bone formation during the growth stage. Human studies also documented an ability of pears to reduce the risk of type-2 diabetes.

100g of pears also contain between 27 and 41g of phenolic compounds (antioxidants, in other words) including anthocyanins – a type of pigments that give bright fruits and leaves their colour.

The amazing thing about these flavonoids is their ability to protect the body from oxidative stress and, as a result, control and reduce the risk of inflammation and chronic illnesses. In humans, anthocyanins may also reduce the risk of Alzheimer’s while in animals they have been shown to slow down the speed of age-related cognitive decline.

When studies looked into aging dogs, they noticed that dogs on a diet containing anthocyanins could complete complex tasks much better than “controls” and when the diet was combined with mental stimulation the participants improved greatly within two weeks. The animals were also more agile and eager to play, which could have something to do with the antioxidant’s anti-inflammatory effect.

The bottom line – include pears in your dog’s diet whenever you get a chance. Just remember, the high water, sugar and fibre content can work as a laxative, so moderation is important.

Introduce gradually, starting with a tiny bite-size piece and gradually building up to a thin slice (for an average cocker).
