Get rid of a pup for submissive urination? Why?
There are many makers of belly bands. You should be able to find a kind that will work for him. Change it when you think he has peed to avoid urine burn.
What have you tried to deal with the problem so far? Is this when your husband greets comes home or is it whenever your husband goes near him? The first would be out of excitement. The second would be out of submission (or some type of fear).
