Nothing happens. Black tongue's is due to extra pigmentation, like freckles, and does not alter the dog's personality in any way.
Sometimes, it is just in your dog's genes. If it is black spots, though, it may be symptoms to a mouth disease.
The Chow Chow is the most well know purebred dog with a wholly black or blue tongue, but the chow is not the only breed with a black tongue. The Chinese Shar Pei also has a blue/black tongue.
There is no such thing.
yes
Some dog breeds actually have black (or blue) tongues and gums. Ask your vet if the coloration in your dog is normal or not.
your tongue turns black
no that's rubbish
He gets splinters in his tongue
It's a hot dog tongue
You get all crazy and stupid like a black person
They can. Black on the tongue is due to extra pigmentation, something every dog breed can experience, including pugs.
When you get older it has black hairs from not taking care of it. Its really disgusting.
A dog's toungue should be a light sahde of pink.
