Pooch problem - a little advice please!!!?

It is most likely a dominant thing because if he was potty trained and suddenly regressed its probaly because hes marking his territory lol I have a husky pit mix so i know how important it is that you stay in command ;) but this will stop if you can teach him that You are pack leader not him. It may take a minute to teach him that but it will probaly help and you shouldnt have to get him fixed. I have never fixed any of my dogs and its never been a problem to me or anyones female dogs as they dont go out with out me lol anyway here is a good website for you www.dogbreedinfo.com/topdogrules.htm GOOD LUCK!!!
