A: Is Charley fixed — neutered? This is an important step to level out a male dog’s behavior. Also, has Charley been checked out by the veterinarian since this new aggressive tendency started happening? There could be an organic reason for his distress, and he’s trying to let you know.
A sudden change in a dog’s behavior is a reason to seek out a medical professional. You might not think there’s anything amiss, and you might not be able to see any source of obvious pain such as a limp. A vet, however, can ask the proper questions about the dog’s health.
