Eating grass, licking, digging, twitching paws in their sleep: eight things dogs do, explained briefly, and when it's actually worth worrying about.

Why does my dog eat grass? And 7 other questions

Dogs sometimes do strange things, and we turn to Google en masse to figure out why. We gathered the most-asked questions and answer them briefly and clearly. Handy for understanding your dog just that bit better.

These are general explanations. If the behaviour changes suddenly or drastically, or you’re worried, discuss it with your vet.

1. Why does my dog eat grass?

Usually this is just normal behaviour. Dogs nibble on grass out of curiosity, boredom, for the taste, or maybe for a bit of extra fibre. Sometimes they do it when they’re feeling a little queasy. As long as it happens now and then and your dog stays in good shape, it’s rarely a problem. If he suddenly eats a lot of grass, vomits often, or seems listless? Then a vet check is a good idea. Also watch out for sprayed grass or toxic plants.

2. Why does my dog lick me?

For dogs, licking is communication and bonding. It can mean affection and seeking attention, but also tasting and investigating, your skin is salty and full of scents. As a puppy, licking is part of contact with the mother; many dogs simply keep doing it their whole lives.

3. Why does my dog dig?

Digging is deeply rooted in dog behaviour. It can be about hiding something (or retrieving it), making a cool spot on a hot day, boredom, or simply because it feels good. If your dog gets enough exercise and challenge, excessive digging usually decreases.

4. Why does my dog whine or howl?

Whining and howling are vocal signals: your dog is seeking attention, is excited, worried or uncomfortable. It can also point to pain or stress. Pay attention to the context, when does it happen, and around what? That usually tells you enough.

5. Why does my dog move its paws in its sleep?

There’s a good chance your dog is dreaming. Like us, dogs go through a dream sleep phase (REM sleep). The typical twitching paws and soft noises come with it. There’s no need to wake them up. Let them carry on dreaming.

6. Why is my dog’s nose wet?

A moist nose helps your dog pick up scents and plays a role in cooling down. The moisture level can vary quite a bit over the day; a dry nose on its own isn’t a reliable sign of illness. Are there other symptoms? Then it’s worth looking further.

7. Why does my dog tilt its head?

That adorable tilted head is often linked to listening for and locating sound, or to paying attention to you. Usually it’s harmless, and even endearing. If your dog suddenly does it constantly, together with balance problems? Then a vet check is worthwhile.

8. Why does my dog chase its tail?

In puppies and playful dogs, this is usually just play and burning off energy. If it becomes obsessive or compulsive, boredom, stress or sometimes a medical cause could be involved, then it’s worth paying attention to.


The common thread: most “strange” dog behaviour is completely normal, and often even endearing. Know your dog, watch for changes, and enjoy their quirks. In the mood to head out together? Discover off-leash areas near you on GoPuppy.
