My pup has two back broken legs. He had surgery 2 days ago and can't walk on them yet. He urinated on himself lying down yesterday. His balls turned red. I gave him his meds and it went away. But they're starting to get red again (he didn't pee his self this time) but I can't give him his meds till later tonight. But Could that be the reason (urinating himself) ? Should I be worried ?! How can I help?
