Basset UTI

My poor boy has a UTI (urinary tract infection) shortly before Christmas, he was having lots of uncomfortable and uncontrollable urination. We caught it pretty early and he took his antibiotics but today while he was sleeping he wet himself. I’m thinking he must have another UTI.

Is this common for bassets? Our theory is he squats to pee, and maybe he is catching germs off of the ground. It’s the rainy season in Oregon so there are little puddles in our yard of standing water. He will be 2 in August but too this close together has to be related.

He eats royal canin medium, he has access to clean water all day, and he does drink a lot. I just don’t know how to help him not get infections.
