I agree. Milk? Although if that were the case, it shouldn't be there for long. Is it possible that it is thrush? Stabbing in the dark so don't panic about it, as I'm likely to be wrong.
ETA: I think you did well to take that photo single-handedly. My memories of my (now 1 yo) boy's puppy teeth are still very vivid and I still carry the scars of puppy teeth marks on my hand LOL!
Glad black spot isn't a problem ;)
No milk involved. She has been on pasta and vegies with a handfull of dry. Also gets chicken wing or neck or carcus.
It took about 10 shots to get that photo, and a little bit of pain
Have to go back to vet in 4 weeks to get 3rd injection so will wait and see what happens with white on tongue.
