I have a female Golden Retriever 12 yrs old, good health, that has had UTIs over the years. Most recent occurrence resulted in trip to vet, antibiotics. After 7 days of antibiotics, she had some serious straining one day, & vomitted her medication. Otherwise, very active. The next day, however, she made not attempt to "squat" to urinate, but after sleeping in her dog bed, I found it wet with urine... no blood. This has continued for 4 days & she is now at the vet, but wondering if there may be something they haven't thought of as they say it's "just a UTI".
