Sasha is 9 months old, and was spayed 3 weeks ago. She has been "house broken" for a long time now - she hasn't had a single accident for about 3 months, and before that it was only every now and then. She's recovered well from her surgery 3 weeks ago, but during the last 5 days she has started having accidents in the house. She's NOT going all the time - still going to the toilet about the same amount of times in the day as usual...just inside! I thought at first her training had slipped, but the last two days she has also peed in the house during the night, as if she can no longer hold on all the way through the night. She has had three accidents during the day, and one of them was when she had told me she needed to go out, and JUST before we got out the door she squatted. I told her "no" and she stopped, and waited till we were outside. It's really weird - I don't understand what's going on...has anyone else experienced this???
