I adopted a schnauzer/terrier mix that is about 2 yrs old. She is healthy and active, I work so she is in her kennel during the day but gets plenty of exercise when I am home. Now she goes only in the afternoon on our walks, both urine and bowels. She seems fine, the vet says she is fine but I worry that this may not be a healthy schedule. I would like input as to whether this is all right.
