This practice needs to change the way they do business. They are either extremely incompetent or extremely unethical. I think it is both. My other dog had a urinalysis left on his plan so I brought in a specimen to test because he had been getting me up at night to go out. After testing I was told they could not tell if he had an infection so I would need to bring him in so they could insert a needle into his bladder for another specimen. This sounded dangerous and unnecessary to me. They also said they found crystals in his urine and he needed x rays of his bladder to check for stones. I took him to another vet for a second opinion. They were able to test the specimen I brought in and determined that he did not have an infection and there were no crystals in his urine. The most likely cause for him going out at night was because he was not drinking water during the day and drank excess water at night when I got home. The remedy was to give him crushed ice (which he loves) in the morning to keep him hydrated during the day.
