ShihTzu Urination

August 11th, 2007, 08:35 AM
Our 12 year old ShihTzu recently started drinking more water than usual and would have problems urinating, on himself, in his bed or under our bed where he goes when scared. This recently started during the summer Florida thunderstorms and only when he is home alone. The vet checked all blood levels and kindey functions; which were normal. We believe this may be because he is afraid, lonely, or just getting older. Any insight or suggestions would be appreciated. thanks.....

I am glad that his blood work is all within normal limits. Was a urinalysis performed at the same time? There are over a dozen causes of increased water consumption - most are easy to see on blood work however there are a few common ones that need additional testing. Also a urinalysis might answer that the amount of water consumed is normal for him. For example, infection of the bladder or kidneys can lead to increased water consumption with normal blood tests.

If it is from fear, then sometimes in older pets there can be vision or hearing impairment or arthritis. These condition can make life a little more scary but also a little more difficult to go out to the restroom.

Just some thoughts. If any of these seem like they may apply, it would be a good idea to recheck with your veterinarian. :pawprint:

Dr. Lee:

Thanks for the information. Something we discovered last night is he urinates on himself while he sleeps; at least he did last night in our bed which he has never done before.

We plan on getting a UA done but thought I would add this bit of information.

If it turns out that testing is consistent with incontinence, then there is great medication which is inexpensive, safe and works well. Phenylpropanolamine (PROIN).:pawprint:
