I took my wife and daughter to look at a puppy this evening, a female, 6 months old. She was energetic and had a good coat but she had a cut on her rear leg that looked a few days old - already scaring over - that had not been treated. By itself the cut didn't represent reason enough not to consider the dog, a vets visit in the morning would have been all that was needed. What concerned me was a growth on the back of her foreleg, behind her elbow (if dogs had elbows). The breeder said it was from the kennel and that it was not unusual and it would go away. The growth felt soft like fatty tissue and didn’t seem to hurt the pup. I’ve seen kennel sores on older dogs- they are usually callous and bare but I've never something like this on a puppy. Is this a common and temporary thing?
