Hi , flopsy has sadly been diagnosed with dental disease . He recently had surgery to remove his incisors . Unfortunately he had to stay at the vet because the site got infected . After they treated the infection he was allowed to come home . He is taking a lot of anti biotic so. He is eating and healthy but I have noticed that his pee is red . Is this just because of the anti biotics?

Red urine (due to excessive urinary pigments) may occur due to any of the following: While on antibiotics At the first cold snap in the fall After eating fir leaves After eating carrots, spinach or other veggies containing beta carotene So, it is likely from the antibiotics. I would be overly concerned at this stage but I do suggest you call your vet and let them know so you can get their advice since they have all of Flopsy's medical history.
