I have a 12 year old Beagle. He has had severe UTI’s in the past (passing blood clots) and it seems that since then he gets them more frequently. I notice that today he started asking to go out more often, was drinking more water than usual, and only urinating small amounts at a time. I would like to be proactive, and head off another UTI. I know in humans that taking cranberry can fend off a UTI, is there anything over the counter or holistic that I can give my sweet boy that won’t interact with the phenobarbital he takes for seizures?
