I stopped giving my dog the tramadol,it just wasn't agreeing with him. The metacam is just fine. Now I have a new problem. I do not believe my dog is in any pain. he gets up in the morning at 6. he eats, does his business and everything is fine until around 11am then he does this huffing and puffing,which he has always done all his life until he gets what he wants.But now He continues doing this for about an hour or so,then he lays down and naps for an hour.When he gets up from his nap, he is fine until around 5:30pm. he starts in again. Around 7pm I take him in the yard to do his business and give him his medacam. He then goes in his bed and sleeps till 6 am Can anyone figure this huffing and puffing out,is it anxiety? I am going out of my mind to please him. I am so stressed, I keep thinking maybe its time to put him to sleep, but he is fine in every other way. Any suggestions?
