I have 2 dogs that I am retraining and am so frustrated I could pull my hair out. If they were not such a comfort to my husband they would be gone. We had them trained and then we had them fixed and ever since it is back to ground zero and this has been a year and a half ago. It is starting to get better now but good grief, I have always had cats and dogs inside and never had such a problem. The vet said that the surgery could not have traumiotized them being males but what happened?
