The majority of dogs go into an almost ecstatic, euphoric state from ear scratching.

This is why scratching your dog's ears is so enjoyable

For years, alternative medicine practitioners such as acupuncturists and acupressure therapists have often worked on the ear. But why? Because the dog's ear contains a complex network of nerves that connect to internal organs and transmit impulses throughout the body. This 'body map' in the ear allows alternative therapists to effectively treat the dog's entire body, explains Dr Christine Makowski, a veterinarian in Pennsylvania. With this in mind, it's easy to see that a dog's ears are extremely sensitive to touch.

Ever had your dog almost go into a trance or doze off while you scratched his ears? Nerve impulses passing through the hypothalamus and pituitary gland release endorphins - the same pain-relieving, feel-good hormones that humans produce, for example, during exercise. These substances completely relax, calm and make your four-legged companion happy.

So when you scratch your dog's ears, he's actually getting high on his own hormones," explains Dr. Allen Schoen, Director of the Center for the Development of Alternative Therapies in Veterinary Medicine. The expert says ear rubbing satisfies dogs' basic need for human affection and communication. But our pets can be picky about who they are willing to accept this delightful ear scratching from.

Not all ear scratching is a source of pleasure

Although dogs generally like to have their ears scratched, this does not mean that they will welcome it from anyone. According to the book The Secret Lives of Dogs, dogs are very selective about who they touch. The outstretched hand of a stranger can easily make them tense or nervous. To understand this, you need to know that dogs interpret head height and head touch as a dominance signal. (This is one of the reasons why head pats and hugs do not have the desired effect.)

Think about it: a submissive dog will often crawl under another and gently rub against it - a sign of respect. Conversely, when a dog puts its head on another's head, it's a gesture of authority. Likewise, a human putting his hand on the dog's head or stroking his ear may be interpreted as dominant behaviour.

How to use ear scratching for pleasure

When it comes to teaching your dog, you don't always have to reward him with a reward wall. A gentle ear scratch and a complimentary "good job" or "well done" can also be positive reinforcement. Such positive feedback - whether it's treats or praise - will encourage your dog to behave well in the future, or to perform tasks the way you want them to.

Sometimes a little ear scratching can be even better than a treat. Even though the way to a dog's heart is often through its stomach, it still enjoys human attention and a nice touch.

Ear infections are one of the most common reasons dogs visit the vet

Does your puppy basically love it when you scratch his ears, but overnight he can't take it anymore? It's possible he has an ear infection. Your dog's ear canals bend and curve sharply, making them prone to infection. This can be prevented by regular ear cleaning, but if your dog suddenly starts to show pain while you are scratching his ears, you should make an appointment with the vet immediately. Ear infections should be diagnosed and treated as soon as possible!
