My sister’s yellow Labs just got back from the groomer. Pay attention to the one on the left. Has anyone seen this before?

those oddball canine quirks and when it’s time to call your vet. See for yourself:

1. What you’re most likely seeing is harmless pigment

In the vast majority of cases, flat black or dark blue-black spots on a dog’s tongue are just pigment. Think of them like freckles or birthmarks. They can appear as a few specks the size of a pencil eraser, or as larger patches 0.5 to 2 inches across. They’re usually flat, not raised, and they don’t seem to bother the dog at all.

People often associate dark tongues with Chow Chows or Shar-Peis, but pigment spots can show up in all kinds of dogs, including Labs, Golden mixes, shepherds, and plenty of completely ordinary family dogs
