Dog’s nose | Curious facts beyond the boop

It’s not just for cute boops… A dog’s nose is probably one of the most fascinating things about them. So much so that I am dedicating another post to the dog’s nose and incredible sense of smell. 

I love watching my boys noses, how they follow an invisible story, the tiny twitches, the hunger of the unknown and exciting information they greedily breathe in. They are both into this ritual, yet I often wonder how Coop and Fred perceive this world based on their experiences of scents.

Coop is certainly a good sniffer, but the boy is mostly interested in pee mail. And flowers. Fred, on the other hand, has the nose of canine dreams! He doesn’t care about the mail, but he always informs me if somebody we know is around the corner, a dog just walked through the village, or there’s a cat, bunny or pheasant nearby (by “nearby” I mean distance on Fred’s sniffing terms – it covers miles…) And both are definitely aware of food smells and do react to any emotional and hormone-related changes in us.

We know that dogs rely on their sense of smell and hearing more than vision. Does it mean that even my chaps, whilst being canines, would actually see the world around us as two completely different environments? The geek in me keeps playing with this idea a lot. 

But is it exactly that makes a dog’s nose so unique?

It has about 250 million receptors responsible for detecting scents. Humans only have 5 million. We are pretty basic.

Dogs can bond with their littermates and humans through scent and detest strangers and non-litter pups because of it. In a study a dog was presented with 5 different scents including his own, a familiar human, a strange human, a familiar dog and a strange dog. Only the scent of the familiar human triggered the response in the brain area responsible for positive emotions, rewards and “romantic interactions”. In other words, the pups knew who is responsible for the biscuits. 

Even more fascinating, dogs can differentiate between two identical twins if the twins were fed different diets or raised in different environments.

If a teaspoon of sugar was dissolved in two Olympic-sized swimming pools, dogs would be able to smell it. 

Dog’s ability to sniff is breed-dependent. In a 1965 experiment by Scott and Fuller, a mouse was left in an acre-sized field. Beagles located it within a minute. A fox terrier took 15. A Scotty literally stood by the mouse and still failed to see it. I suspect if a bloodhound (the clear champion of sniffing) was around he’d be by that mouse in seconds.

Cockers, on the other hand, proved themselves as fabulous drug detectors.

Dogs can track a person days after his or her disappearance as long as there’s about 1/1000 of human scent left on the ground. 

They can also confirm or deny if two odours are from the same source, identify separate ingredients in a bowl of soup, or detect substances used in explosions despite the presence of any debris. 

Dogs can smell cancer, covid, changes in blood sugar or body pre-seizure. 

A blind dog will always follow his nose. It is what can help him adjust to his new life and stay tuned in without panicking.

Dogs smell better in humid conditions, and struggle to smell effectively when they feel really hot.

Dogs who frequently eat coconut oil may have a reduced ability to detect scents

And canines diagnosed with hyperadrenocorticism, hypothyroidism, or diabetes can also struggle to use their nose as nature intended.


Next time you look at your pup’s snout, take a moment to appreciate its wonders that we will never experience or truly comprehend… And follow your dog’s nose…

Be more dog. A few simple secrets to better understanding & training your spaniel

Do you speak Dog? I know, I know, odd question to ask… But bear with me.

A few days ago, as we finished our little training session, I wondered how much my perception of training has changed over the years. Once upon a time training a pup a few basic commands felt, well, basic… Nothing much. Treats, gestures, cues – job done! 

But as the years passed by and the volume of digested books, studies, courses and experiences settled in my brain, I realised a simple thing – training a dog – and especially COMMUNICATING your idea to the dog effectively – is far from simple, rrrrrrreally far from simple.

More often than not (and here I am talking about regular pup parents like you and me, not professional trainers) getting a pup from A to Z feels like a three step process: the treats and lure, the results and the added cue or gesture or both. Creatively speaking, we see training as Malevich’s Black Square. 

For a typical dog, on the other hand, our efforts are likely to resemble something painted by Dali…

The smell. The dog smells all the distrastive, often invisitable to us, thing around him. He also knows that you have treats in your pocket. He knows what sort of treats they are. He smells your emotions. 

The taste. It makes the brain happy. And the pleasure should be immediate otherwise there’s no point. 

The sight. He watches you most intensly than you’d dare to know. For a dog, it’s not such a cue -> a treat link. It’s also everything in between (it’s known as bridging if you want to be clever). The position of your body, your hand, your eyes, facial expression, any movement you might make, the spot where the treat is placed and received. All these matter to him and will be remembered carefully because  he needs to remember exactly what, when and how gets him the treat.

The sound. Dogs are a creatures of a few words. They like it simple. The first word is to get attention. The second one is to determine an action. High pitched sounds can mean excitement or alarm. Longer (stretched like legato in music, think “staaaay” or “gooood boooy”) words are to slow down, calm, stay still, relax… 

The emotions. Happiness, fear, excitement, stress – all these emotions cause a burst of different hormones that will have an effect on the pup’s ability to concentrate, learn and remember. 

What does it all mean?

For me, communicating an idea to a dog successfully involves a few simple but important points…

… only train when you feel happy, relaxed and well (otherwise the dog will sniff out our own hormones, especially stress hormones – and will mimic them)

… only train when a dog is happy to be trained – he is rested, happy, adventurous, excited and eager to learn

… keep the duration of training based on your dog’s abilities. Do not let him get tired or bored. Think how you’d feel if you were made to sit through a two hour lecture – even if it’s really interesting in the beginning, the brain often gives up on living after an hour unless there’s a break

… watch your own body language – record your sessions if necessary

… use the right tone of your voice depending on what you want to achieve and, please, do not get into the “machine gun”mode saying to your dog “sit, sit, sit, sit” or “come, come, come, come” on repeat. One word – long pause – another word if needed. Otherwise your pup will just hear “comecomecomecomecoooooome” the same way we hear “yap-yap-yap-yap” – it’s just another meaningless and slighly irritating noise…

… choose treats wisely. You don’t need to have a whole bag of high value treats! Mix them up! I use kibble, but if we need high value or more attention, add a few tiny pieces of cooked chicken breast and mix them all up. The kibble get a bit of an extra “flavour”. Everyone is happy

… be precise. Reward within 1-2 seconds with easy-to-swallow tiny treats, with precise action, at precise spot and accompanied by specific word and specific praise. Eventually the praise will (or almost will) replace the treat teasing the pleasure center in the brain with a sound alone. 

Simple? Yes, once you know the why’s and how-to’s. Now all you need to do is to remember these points while putting them into action. And that’s when things suddenly get as complicated as learning and practising a foreign language. It takes an effort but suddenly and eventually everything falls into place.

Dogs tend to play more with each other when their owners watch them, eye contact and engage / Perfect cocker spaniel (C) Canine behaviour study, english cocker spaniel dog blog, puppy tips, behaviour, spaniel grooming, cocker spaniel health

Watch me if you can

I love watching my boys play. In all honesty, I could do it all day long – if only they felt like playing all day long. Seeing them happy and carefree is my source of endorphins. And now it turns out, my presence does a lot of good for pups, too.

According to a study published in Animal Cognition magazine, our dogs are more likely to play with each other if we pay attention to them instead of leaving them alone completely or simply being present in a room.

The researchers observed 10 pairs of dogs who lived together for at least 6 months and were known to play with each other at least once a day. During the study, the dog parents did not use toys or encourage them to play specifically.

But whenever a person was around offering eye contact and occasional praise, the dogs were much more likely to start playing and having fun. The situation was different when a person was not in the room or was present but stared at his phone or computer screen.

The scientists suggested that this dog behaviour might have been caused by several factors including potentially seeking owner’s attention in a manner of little kids, feeling safer, hoping that the owner would join in, or possibly having a release of oxytocin or the “love hormone”.

This is a type of study that “leads to a lot more questions than answers”, but it is obvious that being with our dogs, being present when they seek our attention, is a wonderful way to make them happy and strengthen the bond between us and our pups.

Just like the immortal lyrics go… “Every single day… every game you play… I’ll be watching you…”
