Dog pees when laying down.?

Loose bladder. Could have been caused when she got spayed.

This can sometimes happen to spayed dogs. Usually later in life.

There is a pill called Proin which helps greatly with this problem.

I strongly advise having your dog seen by her Vet. They can examine her & determine the best course of action. There might even be something else wrong.

Some general information that you might find helpful to look over. I had this issue with one of my older females. It can be trying at times but gathering as much information as I possibly could made it easier.

Again, a Vet will always know best. I just wanted to throw some general info out there.

Many spayed women people improve urinary incontinence as they age; call your vet. He would have some therapy for it. i think that there are some drugs which could help some dogs.

This is actually quite common. Just go to your vet and tell them all of this. They can get her on some hormones to stop this.

If your dog is urinating uncontrollably, she really needs to see her vet. Does she seem to feel okay? Eating, drinking, playing? (Hope she'll be fine) :]
