I have a 14 yr and a 12 yr GR. The last year they have both come down with 2 UTI's and I just came home to a mess. I know the older girl has another and now I suspect Zek has one too. Started meds last nite for Jaz, taking Zek to vet tomorrow. They have not had these throughout their lives, just as they have become elderly. They have had blood work done and are fine. Eat fine and act fine. I am going to pay a dog sitter to start coming out at noon to let them out. Everyone holds it for 8.5 hours M-Thru. I suspect that is too long for the elderly-hence the doggie sitter. They have both been holding it fine at night from 9 to 5:30. Is it more common for older dogs to get UTI's?
