Is feeding one meal a day going to reduce the risk of age-related illness in dogs? Looking into the November 2021 study, how many times should you feed a dog, adult and puppy, number of meals, quality of meals, stress and diet in dogs, feeding dogs depending on size and breed (C) Natalia Ashton / Perfect cocker spaniel blog / English cocker spaniels, puppy tips and advice, grooming, training, behaviour, diet / Qualified canine nutritionist and small animal pet nutrition coach UK

How often should I feed my dog?

Feeding a dog, especially, a cocker spaniel, should be easy and straight forward. You choose the ideal food like 12345, set times and see your gorgeous pup enjoy his meals. You think you’ve done everything right, and then comes a study suggesting that your dog should only eat once (which sounds a bit like a promo for another Bond film, really). Even though the study itself specifies that more research is needed, the media picks it up and spreads all over the internet telling people that they are literally crippling their beloved pooches.

What happens next?

Dog parents all over the world suddenly feel scared, confused and upset because who wouldn’t?

Luckily, we can talk about it here to clarify a few things and make life a little bit brighter for everyone, including pups who are probably holding onto their bowls right now panicking about losing the other precious meal they’ve loved so much.

So what did the study say?

The Dog Aging Project study published in November 2021 suggested that dogs fed once a day would be less likely to get diagnosed with age-related health issues. The study was based on three facts: dogs are from wolves and wolves don’t eat like dogs, intermittent fasting is good, and dog owners’ annual surveys gave positive response.

Now, let’s remind ourselves once again that thanks to evolution, changes in lifestyle and artificial breeding, dogs and wolves are not exactly the same. An average grey wolf lives between 6 and 8 years. Some may reach 17, but chances are slim because of the natural selection.

Intermittent fasting in laboratory animals may did them favours, but those animals are not living in the same environment or enjoy little pleasures of life as our pet dogs. It’s also worth to mention that most of the reference fasting studies were done on humans or rats. And true, we can do well with intermittent fasting done right. But even humans, when they do intermittent fasting, only follow 12-16 hour fasts, not 24! And, as humans, we do it at our own will and understanding of what is going on.

I don’t take owner’s surveys seriously at the best of times. Everything people think and feel about their dogs is biased and based on opinions, understanding, education and experience of each particular person. Even if we talk to 24000 of them, as the study did, it won’t rock my boat as a scientific fact.

I was also uneasy about two other factors. The study only used neutered dogs. And for me it does not make sense because their body functions have already been altered and thus any outcomes would only apply to other neutered dogs. And we know that neutering isn’t all fun and games. It does increase the risks of disease including several cancers. The other factor is that 56% of the dogs used in the study were mix breeds – in veterinary terms, they were mutts. Whilst I have no issues with loving all dogs, I would struggle to apply any study on mixed breeds dogs to changes any pure bred dogs would need to go through in order to live longer? Because… genetics… And among the breeds, many of them were large breeds that would feel comfortable with one meal a day, theoretically. Because… labradors and retrievers do love food.

How many times do we need to feed our dogs each day?

This will depend on several factors.

First of all, your dog’s age. Puppies need to be fed more frequently, 3-4 times a day, because it will allow their little bodies digest food comfortably (as their stomach is still growing), receive nutrients and calories (that are higher than required for an adult dog) how and when needed and, and as a result, help them grow at a steady rate. This alone will reduce the risk of obesity, bone disease and even some cancers in the future.

Most healthy adult dogs aged 12 months or over can eat twice a day with 8-12 hours in between. This will allow their stomach to digest the meal, keep the pup fill full and happy, then naturally empty and signal the brain the hunger “Must eat or look sad!” cue.

Breed is important.

Not only dogs would require different quantities of food per day, they will utilise what is given depending on their size! When a study looked into 69 clinical parameters in dogs of various breeds, 16 (including gut bacteria, specific proteins and antioxidants) were different between the large and small canines. Overloading the system by giving dogs one meal a day means that some of these dogs are even less likely to absorb the nutrients that could be vital for their long-term health.

Cockers are usually fed twice a day, but they are foodies and most of the dogs I know, including my own, would feel depressed, stressed or anxious if they suddenly lost a meal and had to go on empty for 24 (!!!) hours.

And what can happen to a stressed dog?

First of all, he will be so anxious about the next meal, he is likely to inhale it. This can lead to bloating and be life-threatening.

In fact, when a study looked into causes of bloat (or gastric dilatation-volvulus syndrome), the one-meal-per-day, fearfulness and stress were three of the highest risks.

If your dog has psychological issues such as separation anxiety, reducing the number of meals can cause release of stress hormone and make them feel worse as they lose their “comfort food”. Currently, about 20% of dogs are known to suffer from SA, 20-25% are fearful towards strangers (read – possibly have a build-up of stress hormones in their little bodies on a permanent basis) and as many as 50% may have noise sensitivity (again, read – stressed out regularly). Imagine if all these pups lost one thing that makes them feel good?

Even if, hypothetically, a one-meal-a-day diet could reduce the risks of some age-related diseases (which to me could be fixed and prevented with many other and much less dramatic diet and life-style changes and alternations such as, for example, not feeding dogs high protein or grain-free diets or avoiding so called “superfoods” known to cause kidney stones, or measuring dog food to prevent obesity – one of the major factors in age-related health conditions and cancers in dogs that the study did not even look into), it will cause great stress. Stress, in its turn, will lead to an absolute havoc within the body and affect every single system, from changes in hormones and digestive enzymes, blood sugar control and vitamin and mineral balance, to the bones and muscles, the nerves and brain, blood pressure and heart. Which does not immediately screams “healthy dog” to me.

What should you do about your dog’s meals?

If you have a puppy, stick with 3-4 meals a day until he is 6 months. Then, in case of cockers, try with two meals but if your puppy struggles, go for three. It is more important to watch the quantity of food per day rather than number of meals required to eat this food.

Do not feed your dog, especially a puppy, “free style” better known as ad libitum, by leaving a bowl of food for the entire day and allowing the cocker to help himself whenever he feels like it.

Set meal times are important for digestion, elimination and overall satiety. In other words, a fed cocker is a happy cocker who knows when to eat, sleep, poop, play and repeat.

If your dog has been diagnosed with any health conditions or has to take medication, you will always need to consult your vet about feeding times.

Remember that any health-related advice you’d even need should always come from your vet. This alone will keep your dog healthier for longer.

Update on avocados in canine diet and pet food. Avocado as ingredient in dog food, benefits, side-effect and risks when dog eats avocado (C) Perfect cocker spaniel blog by Natalia Ashton / canine nutritionist & pet nutrition coach / Breed, grooming, diet, nutrition, puppy training and behaviour information

An update on avocado in dog diet

I wrote about avocados and what they can do if a dog eats the fruit back in 2018. Three years on and the idea of including avocado in pet food is becoming a reality. Some companies are using it based on nutritional benefits of the berry, others rely on avocado meal as a fibre replacement for beet pulp or cellulose. But does it mean that avocado is good for our spaniels?

Essentially, avocado is still considered toxic to dogs by WSAVA, ASPCA and veterinary manuals. As I’ve previously written, the fruit, skin, leaves, stems, bark and stones are high in persin. If you give persin to a human, the substance may actually fight cancer and increase effectiveness of cancer fighting drugs. If you give it to an animal, including dogs, it can cause an accumulation of fluid in the lungs, breathing difficulties and death. Small quantities of the fruit will lead to diarrhoea and vomiting. The high fat content will increase the risk of pancreatitis or weight gain (and cockers are genetically prone to both). And the stone can cause obstructions or, if it’s crushed, repeat the worst-case scenario as above.

Of course, the parts of avocado contain different levels of toxin. Leaves and bark are the worst. The light green flesh you’d use in a guacamole, is least toxic, which does not make it safe – it simply means you are less likely to lose your dog. Studies have shown that feeding dogs small quantities of avocado didn’t always make the canines unwell visually, but their bloods had elevated levels lactate dehydrogenase, alanine aminotransferase and alkaline phosphatase. When rats were given avocado oils in another study, their livers showed abnormalities.

What is also important to consider is that avocados are usually used in pet food in a form of meal. And the meal can contain any parts of the plant due to natural contamination during manufacturing process. In other words, you may be lucky and have “light green parts” or not to lucky and give your dog a treat or food containing traces of bark or leaves.

Does it mean that avocado is bad? Avocado is a fantastic source of fatty acids (the “good” fats), vitamin A, E, K and folate, minerals magnesium and potassium, as well as fibre. It’s packed with antioxidants, too. But this only applies to human diet.

This also means that simply because something is really good for humans, it does not necessarily need to become an ingredient in canine diet.

And please do check the ingredients list on your dog food and treats to ensure that they are avocado-free. Maybe one day there will be long-term studies to prove us wrong or a new process developed to make avocados safe for dogs. But honestly, why not simply focus on other sources of the above mentioned vitamins and minerals that are known and proven to be safe for dogs than trying to alter a fruit known to cause problems. Not everything in nature is meant to be tamed to suit the human brief or financial interests. But that’s how I feel about it.

Corn maize in canine diet. Can dogs eat corn? Pet food insights and advice on choosing dog food. Genetic modification, hybrid corn, pros and cons of using corn in dog diet (C) Nutrition for English cocker spaniels, Perfect cocker spaniel blog / Natalia Ashton, canine nutritionist, pet nutrition coach, small animal nutritionist UK

Can my dog eat… corn?

What is yellow, has ears and can be used to make food, coffee, fireworks and fuel? 

Yes, today we are going to talk about corn and the role it plays in dog diet. I know corn often gets bad press and has been dismissed by many pup parents because the grain is often presented as “the worst” ingredient in dog food. But is it really?

Let’s discuss a few curious facts today.

Corn isn’t just a “filler”. Corn is a nutrient-rich grain that adds proteins important for body’s growth and maintenance (the grain is 6.8-12% protein), carbohydrates for energy, fibre for healthy digestion and potentially reduced risk of GI cancers, antioxidants such as carotenoids to protect and strengthen the immune system and, importantly, linoleic acid that is essential for dogs. 

Based on the amino acid content, corn has a biological value of 74, almost the same as beef and chicken (both are 75). When combined with other sources of amino acids, corn can help create food with the gold standard value of 100.

Dogs can digest corn because they evolved and became omnivores that have a genome different to the wolf’s, particularly when it comes to digestion of carbohydrates. When fed a diet containing corn starch, dogs showed 99% digestibility of the starch and 87% of the protein (the highest digestibility compared to diets containing other grains). The diet containing corn flour showed 98% of carb digestibility. 

Corn is not going to cause an allergic reaction in every dog. I have talked about allergies in Perfect cocker spaniel in detail and dedicated a chapter to it in Beyond the Doughnut too. 

If I am to put it all in a (long) sentence – grains are least likely to cause allergies in dogs and corn is considered an “uncommon food source of allergens”, the type of corn used in food production plays a role (in a study dogs with potential allergy to corn were less likely to react to cornstarch than kernels and flour), there is always a small chance of a dog reacting to ANY food ingredient simply because dogs are unique and there are several diet, lifestyle, health and genetic factors that can contribute to the reaction, just because a dog had a reaction to some food where corn is an ingredient, it does not mean the dog reacted to corn, the only way to know for sure is through extensive and labour-intensive veterinary exam, months-long elimination trials under veterinary and nutritional supervision and a review and potentially complete overhaul of the environment the dog in question lives in.

Corn may lower glycemic response in adult dogs meaning that dogs will not have insulin spikes following a meal.

Corn can be a very useful ingredient in a diet formulated for dogs with diagnosed health condition or dogs undergoing tests or treatment. If you vet prescribes a food made with corn, he is doing it to help your dog, not because he’s got an evil canning plan!

But before you rush and grab a bag of dog food made with corn, remember the following…

The corn used in pet food is often a hybrid type that may be higher in proteins and lower in phytates. This, however, means that corn used in dog food, may undergo genetic modification, which can put many people off for a number of reasons. The subject is controversial, especially when it comes to pet food industry because long-term studies of GM corn and its potential role in cancers are lacking. 

If you are concerned, look for UK and EU produced foods and check the label. By law “animal feed materials and compound feeds which contain GM or GM-derived material must be indicated on the label”. And even though many ingredients, including corn, are exported from the countries that allow genetic modification, the UK/EU rules will highlight this for the consumer.

Corn can be a source of aflatoxins and at the moment the official recommendations and safety limits differ greatly when it comes to grains used for human food and those used in animal feed. There have also been a few recalls due to aflatoxin contamination in pet food, however, not of them were necessarily caused by corn. 

It is worth remembering that pet food manufactures do test ingredients and have measured in place to ensure food safety. There have also been considerations for the use of special supplements such as Hydrated sodium calcium aluminosilicate, which is natural clay that coats the food and prevents potential aflatoxin poisoning even if the food is contaminated. 

However, according to the review by Maxwell Leung et al. published in 2006 “government regulations of mycotoxin contamination are often compromised by the analytical detection limits, regional prevalence, as well as trade relationships amongst different countries instead of fulfilling the scientific approach of risk assessment and safety determination”.

If you are concerned, buy the food produced by PFMA-registered members. Personally I would stick with bigger food manufacturers that have resources and facilities for testing ingredients and products and actually inform their customers of food recalls should the worst happen. 

Choose shops that are more likely to store the food with great care.

Check the label on the bag for best before date and keep the food in a cool, dark place, and use the bag the food came in – just remember to seal it well.

And if you choose to make treats with corn for your dog, shop in supermarkets for organic polenta or organic corn flour known as masa harina.
