I have a 1 yr old male bichon frise. I have noticed this evening that he is quite bloated and constipated. He's not his usual chaotic self. He's still eating and drinking and peeing no problem but as I said he's constipated. He has had a big poo but it took him a while He's on 5mg Prednisone a day and I feed him royal canin anallergenic as he has allergic skin disease. He's currently on an elimination diet so I can't really give him anything like pumpkin to help him go. Other people in the house are like 'we'll see how he goes'. I'm kind of worried, thinking bloat, but he's able to pass stuff in a fashion. Also releasing gas from both ends like a trooper. Any ideas? He's got the vets Wednesday anyway.
