Tyson, who is 3, is completely housetrained. Usually, he'll come let me know when he has to go potty. He was great the first week I had him. Now, whenever I leave the house, I come home to accidents! At first I thought maybe I wasn't keeping him outside long enough. It's gotten to the point that no matter how long I have him out, or how often I take him, he's always pooped & peed in the house when I come home. It's not even that I'm staying gone long, maybe an hour, 2 at most, when I have to run an errand or go grocery shopping. I'm so frustrated tonight, that when I realised he's peed in the carpet, I put him in his kennel. I don't want him to think he's in trouble if I have to put him in his kennel when I go back to work, but I don't know what else to do! Any advice would be greatly appreciated. Thanks in advance.
