Occasionally when my Chihuahua uses her pee pads her bottom becomes saturated with pee and it drips off of her making everything smell. Have you every heard of this problem before?

Hi. I am not sure where to start and I saw your web site so I thought I would give it a shot.

I have a female Chihuahua. She is a little over two and she is fixed. For some reason about 5 months ago when she would pee on her pee pads (this is when she is inside the house. She does also "go" outside) the pee would saturate her bottom and her tail. Her sleeping area, not to mention other areas around the house would start to smell like her pee because it was dripping from her bottom\tail area and it would get on everything. This went on for a few months Then it stopped. However it just started up again. Do you have any idea what could be causing this? The vet, who also has Chihuahuas, has never heard of this problem.

Thank you.
