I can be a little OCD with pets getting sick (and had a really bad experience in the past with two cats getting sick with colds and about a $3500 vet bill when I had no efund...not smart). So ever since I easily freak out when a dog/cat gets ill.
Flanangan (our two year old Irish Setter/Golden Retriever X) is super house trained - and hasn't had an accident since he was a wee pup. Today I took him and our French Bulldog out to our backyard and he didn't pee in spite of being out there for five minute (normally he goes in the first 10 seconds). Later my hubby came home and played fetch with him upstairs. Flanagan lifted his leg and peed and even though DH interrupted him (which would normally stop him if this was done outside) he could stop. Flanagan peed a whole day's worth. Kind of weird. Other than this one out of character incident there's been nothing wrong with him - a little subdued (but he could be embarassed or ashamed at what happened knowing him) and our Frenchie sniffed his region after he peed.
I'm not sure if my Flani has a UTI and I will likely take him to the vet tomorrow. I'm just curious if your dog has ever had a UTI and if so...what symptoms did he or she have? As well, did you take them to the vet - how much did the visit and meds cost?
