Jaden was spayed back at the end of May. A few weeks ago (six weeks later),I noticed what looked like a blister on her belly near her scar from the incision from the spay. It was a Sunday, so we called the hospital. They did not seem concerned and they said to compress it with a hot towel to see if it goes down. Well, since we brought attention to it, she punctured it. We had to take her in. They found 3 inner stitches that she was rejecting. They told us some dogs just reject them. Has anyone ever heard of this or had this problem?
