I have a 11 month old Aussie/Lab mix. He is a rescue and I got him when he was 6 months old. He had no house training at all when I adopted him. He only pooped in the apartment twice since I've had him and that was a while ago. I took him to the vet and he did have an upset belly so we got him on some antibiotics. However, the issue is peeing. He still pees inside! Sometimes we can go days without. There are usually no signs. He will just squat and pee midplay. I take him out 30-45 minutes after I give him water. If I don't take him out another 30 minutes later he will pee inside. He holds it when I am not home and through the night. I'm getting pretty frustrated. Has anyone else experienced this? Any suggestions?
