I don't know if it is really common, but any breed can get a urinary infection. If he has increased his urinating, I would definately have him checked. A bladder infection can cause bladder stones if untreated. I just went through that with my show girl, and had to have the stone removed through surgery.

I was just wondering is it common for Yorkies to have kidney/bladder problems? My pet is 7 years old and he is urinating quite frequently. Should I make an appointment with the vet?
