Hi, my 5 year old miniature schnauzer Oscar is a great wee guy but almost always holds in his poo. I take him walks in a wooded area and he is so busy sniffing in the long grass that usually after about an hour when we return to the car he does some toilet, but then back home he pumps and needs the toilet. Any one there with a miniature have any ideas or suggestions? I meet another schnauzer & he has similar problems, both are male's
Tks
