What to Do If Your Dog Is a Submissive Wetter
Submissive urination is a common problem and can be very frustrating for dog owners to deal with. It often appears just before puberty, and usually goes away with a little maturity if it's dealt with properly.
Do's and Don'ts
Do keep greetings and departures calm. If she's hysterical when greeting people, wait for her to completely give up trying to get attention before even making eye contact with her. Start with just a little chest scratch and a few calm words of praise. If she starts to lose it, walk away until she's calm again. Give her something else to do, like making her sit, sprinkle a few treats on the floor, or give her a toy to hold so she's already a bit preoccupied when greeting. Do make sure she's been out to pee before greeting visitors.
Don't yell at her, or strike her, or punish her in any way other than removing attention if she starts to leak. Since submissive urination is, by definition, a submissive gesture, yelling or punishments usually result in a dog who has to repeat the gesture to get the message across.
The Chronic Leaker
Some breeds, cocker spaniels for example, are infamous for their lifelong submissive urination issues. This problem seems to have a genetic base, and as such, management, along with training, is in order. Along with the do's and don'ts for the average submissive wetter, you may have to resort to belly bands or doggie diapers to at least prevent the mess (and keep your frustration in check) if your dog is unable to control herself.
