Recently my girlfriend and I went for an extended weekend trip and left our pug Marleau at the Petsmart Pet Hotel while we were gone. He was able to go to doggy day camp during the day and had an ice cream and a kong treat while he was there. On the 2nd day that he was there we got a call from the staff at the hotel telling us that Marleau had blood in his urine. They took him to the Vet and took a culture to see if he had a Urinary Tract Infection. They gave him antibiotics and we have continued giving him the meds since we have gotten back and he has not peed any blood at all. The vet called and let us know that there is no sign of a UTI and that he thinks that the blood was a result of him missing us. Since everything has happened Marleau has been his same playful, energetic/lazy self. Has anyone else ever experienced anything like this and what was the outcome? This is my first pug and I am not sure if this is something normal or something major. The vet seems like a great vet but I am a little uncomfortable with his final assesment, Any advice would be greatly appreciated.
