I am very curious if anyone can tell me an answer to my question without being harsh... I recently gave my puppy Zeus a raw bone. The bone has no sharp edges and is completely natural. Everytime Zeus chews on his bone, he whines. I check their teeth and gums 3 times a day, they are always looking good. (i rub their gums, ears and paws so their sensitive areas aren't so sensitive just in case they do have a problem) He also wags his tail while he chews it... I've tried doing research online, but all I get is that several people have this same whining with their pups and they call it "puppy singing" because they are so happy to have something they love, like chocolate to humans.... I have never heard of this and I don't really know if I believe my pup is singing lol but I could be wrong... Anyone have this issue? Does anyone think there is a problem with Zeus?
