I'll try to get a better picI just got him today the breeder said he did not notice it before and said that the little guy may have injured he leg jumping around and may have pulled a muscle he offered to take him back and refund but I may take him to vet.
Any experienced chin owners can tell me what this is and what I should do? Sorry this is the best pic I could get but I just got a little ebony male and notice he has a bump on his back right leg like knee area?
