Dog behaviours explained

Dogs fascinate their owners with their weird and wonderful habits. Some leave us amused, and others leave us confused. Here are a few common dog behaviours, and what we know about why dogs do them.

Scratching the ground after going to the toilet

You may have noticed your dog scratching the ground after doing their business. One common theory is that it is a way of marking the spot. The scratches may leave a visual sign for other dogs, and dogs have scent glands in their paws, so scratching may also leave their smell behind.

Going round in circles before lying down

Many owners wonder why their dog turns round and round before settling. The honest answer is that experts aren't sure. Some think it is a way of checking the spot is safe before sleeping, when a dog is at its most vulnerable. Others think it helps a dog find the most comfortable position, or a good view of the room.

Rolling in smelly things

Many dogs love rolling in something really smelly on a walk, whether it is fox poo, other dogs' poo or the remains of a dead animal. Often, the smellier the better.

Why do they do this? One common theory is that it's a way for them to disguise their own smell, which would have helped their ancestors get close to prey without being noticed. Experts aren't sure, and there are other theories too. Whatever the reason, it may mean a bath when you get home.

Humping toys

This habit often seems to happen at the most inconvenient time, such as when you have visitors. Humping is a normal behaviour, and dogs of either sex can do it. It can happen during play or when a dog is excited.

If it becomes frequent, or seems linked to stress or excitement, talk to your vet or a qualified behaviourist.

Kicking their legs during a belly rub

Many dogs love a good belly rub. During one, you may notice your dog stretch a back leg and start a kicking or pedalling motion. This is a reflex, called the scratch reflex. Touching certain spots on the belly or side triggers nerves that make the leg move, without the dog choosing to do it.

Understanding your dog's behaviour

Dogs have all sorts of habits, from eating odd things to rolling in poo and wagging their tails. Understanding why dogs behave the way they do helps you understand their instincts and what they need from you. If a habit worries you, or changes suddenly, ask your vet.
