I have a cockapoo who is old and has bumps on his body, all benign. He has one bump on his belly he has decided to focus on. He's chewed it to the point of it bleeding. I took him to the vet and had it looked at by her. The bump was confirmed not to be cancer but it is infected. Problem is he permanently has to wear the cone which he manages to get around half the time. I had the ingenious idea of putting a onsey on him which mostly does the job but he seems to get around the cone and at least licks and pushes against the bump (covered by onsey) and still manages to get to it in one way or another. Short of duck taping it, I have no idea how to deal with this. He won't leave it alone. I've groomed him, bathed him and he still goes at it. I've tried different cortisone sprays yet its like he's a human who has a zit that he can't stop picking. Help............ any suggestions would be apprecaited.
