Well, lately he has been. He's a three year old Border Collie, and in the past two days, he's pissed on the couch. Just cocked his leg and pissed on it. Last night he did it, and he knew he had done wrong. This morning while my mum was in the bathroom, he did it again. We know that BC's require lots of exercise, but there are always times when you don't have time to take the dog for a walk every night. He goes around four times a week, for a good, long run. The other days he gets to play ball we tire him out. When he goes for a walk, no matter how far you take him, he comes home and wants to continue playing. He's very demanding. Plus, he barks to get attention, and if you tell him to stop, he humps your leg. Literally flings himself at you and batters away at your leg, and will continue to do it until you have shaken him off enough times. He's been trained, as have all our dogs, he just seems to be going through his stage where he is disobedient. For those who own dogs, is just a stage, like a toddler stage for dogs? He's a good dog most of the time, we love him to death, he wants for nothing, but it seems he is just ungrateful for the love we give him. Its driving us nuts! Can any dog lovers here give us some tips on how to deal with this?
