I have got a problem with my puppy Murphy and I was wondering if any one else can tell me if their dogs do this too. He is currently 5 months old and he is doing GREAT with his potty training for his age. He almost NEVER has an accident when we are at home since i just leave the slider door cracked and he goes in and out as he needs. My only complaint is that while I am at home I let him run around with me - he usually just follows me any ways. BUT - heres the problem - if I run outside real quick, say to just check the mail or grab the newspaper he will jump up on the sofa look out the window at me and pee right on my leather sofa. It is not the end of the world since I have leather and it cleans right up but I am wondering why he does this since it is obvious he knows where he is supposed to go. It is like he is pissed off at me for not taking him with me for 1 minute. I am only gone for a few seconds but yet he does this - UGH - I am going to loose it if he does not stop this. He will also do it if he is in my truck with me. I will leave the truck on and jump out for 1 minute and he will pee on my center console. Does anyone know why he is doing this and how I can get him to stop besides obviously locking him up when I leave and taking him with me. I want him to know it is wrong and not to do it. I think he is just doing it because he is mad I left him but honestly it is only a second or two. Any suggestions on what is going through his head and how to get him to stop.
