Inside A Dog’s Mouth – How To Recognise A Healthy Mouth

We can tell so much from inside a dog’s mouth but there is a quick rule.  The dog’s tongue and gums should be pink, without signs of inflammation or bleeding and the breath should not be offensive.

For anything else, please don’t hesitate to see a vet.

Here is a very quick checklist of things that you need to look out for inside a dog’s mouth

1. Gums

Have you noticed that the first thing that a vet does when you take along a sick dog is to lift the side of his mouth?

He can tell so much from the colour and texture of the dog’s gums.

Firstly, here is a photograph showing a dog with healthy gums.

However, different colour gums can signify the following:-

Red gums can signify gingivitis, which is a gum infection.

White gums can signify anaemia.

Blue gums can signify a lack of oxygen.

Yellow gums can signify liver disease.

Bleeding gums could be a symptom of kidney failure or oral cancer.


Again, colour is important. The tongue should be pink, with no raised bumps or lumps. A few breeds like the Chow Chow do naturally have black tongues. The tongue should have a clear coating.
