Coco is almost 7 months old. She lost a tooth yesterday, a big canine one, and several others are loose. I know they lose puppy teeth and the vet will be taking out the rest on Monday when she gets spayed. I have been noticing her bottom lip has lots of saliva, with little bitty bubbles in it, on the outside kind of in her chin hair. I am wondering if this is from her teething, like a human baby? She licks a lot and chews all her toys and bones. I assume all this is because she is teething and because she is a puppy. I was just curious.
