How to tell if your dog is healthy by checking its tongue colour

A healthy dog's tongue is typically pale pink and moist, though colour can vary slightly with temperature. Breeds like the Chow Chow naturally have blue-purple tongues. Changes in tongue colour can indicate health issues. Pale tongues may suggest anaemia, while bright red could point to fever or infection. A blue tint may signal circulatory or respiratory problems. Always consult a vet if you notice unusual tongue colouration lasting more than 24 hours.
