Mammary Gland Abcess

I saw a dog yesterday that had a large mammary gland abcess, it was about 8 and 1/2 weeks pregnant, full of puppies, they had taken it to the emergency center the night before and been given antibiotics but now the abcess had opened up wide under considerable tension. The owner was keen to reduce the mess, so I opted to sew the wound under local anesthetic, I am not sure how long the suture will hold. It might have been better to leave it open. But the owner was happy that I had tried.
