Urinary Track Infection

Today, I found out my dog has a severe urinary track infection -- one of  the worst the vet has ever seen, and based on her white blood cells, she's had it for a while. She has been peeing in the house for days, and instead of finding a solution, we have been punishing her. I feel just horrible. 

What's worse, her medication cost $315.00. I might have to rethink not having a job this summer..
