My sister has a westie. He just turned a year old in early December. He has a problem with peeing and sometimes pooing in their house. He will even steal their son’s dirty diapers from the trash and eat the contents(poo) from the diaper. I don’t know much about dogs, so that’s why I come to you guys. She seems to think that if she gets him neutered that will fix his problems and I think she hasn’t trained him right since he was a pup. He also will pee on anyone who comes to their house. (he just does a little trickle-like marking his territory). Who is right? Should she re-evalulate how she is training him or should she get him neutered? (she wanted to stud him out at one point but has decided against this b/c she thinks this will fix the prob)
