My dog Chance very recently got arthritis. I took him to the local pound vet and she prescribed him pills. It’s been about three weeks since then and he’s back to normal in his activity level.

Well, about 4 weeks before his arthritis became noticeable he started to act out. He is very well trained and has been since he was 1 year old. He is now 11 years old.

He is a mutt dog. He is half pit bull and the rest is Rottweiler, border collie, and possible German Shepard.

He knows tons of commands and he has always listened when we tell him to do obscure things. Such as, get off the couch, Get out of the mud, settle down or things like that.

There has been no changes in our lives. Everything is the same as it’s always been since Chance was first brought into our home at six weeks old.

Lately, he has been eating out of the cats bowl, not following normal commands, standing on his hind legs to see what’s on the counter. Also, when I punish him for not listening I segregate him from myself just by putting him in the living room and shutting the bedroom door. When I do this he growls and shows his teeth to me. I do not touch him at all. I stand tall and dominant and tell him to ‘get out.’
His safe place is in his dog bed next to my bed, no where else.

Why is he doing this and what do I do about it?

Do not tell me he is going through “turning” on me. I don’t believe that for a minute.
Oh. The only significant change I can think of is my becoming pregnant but I’m 6 months pregnant and his acting out has only been the past 2 months.
