I have a 12 year old shiz tzu inside all the time and recently has started going potty on the rug. I take him out when he lets me know, but he doesn't seem to be able to hold it like he use to. He drinks a lot of water but doesn't seem to be in any pain as far as I can tell he's very active. What could be the problem?
It sounds like your pet may be drinking and urinating more frequently. This is an important clinical sign we see associated with many diseases and should be checked at your vet. Your vet may want to run some tests to help with a diagnosis. vetcare
