I have a big problem with my male boxer Tyson,my doberman of thirteen yrs passed away two wks ago and now I have a very sad dog that sits by the window and looks for Jillie and now he lifts his leg on my furniture and the corner of my bed now I have them covered up but thats not the point.Its every time I go out now.I have yelled at him,showed him what he did ,gave him a swat on the butt and it just don't matter to him.If i got another puppy would that help or get him neutered.i love him and want to help him.He has his own dog door so he can come and go as he pleases,he has abig fenced in yard to play but no one to play with he is three yrs old .can someone please help me.Thank YouJoey K
