Creatinine 1.81-1.9 with possibly increased thirst
My sweet boy dog is 10.5 years old. We lost his sister in February and he’s always been very codependent. Since around and I’ve noticed he’s drinking more water, though our routine has completely changed. I got blood work and UA in March. His creatinine was 1.8 and he had a few struvite crystals. The vet treated him with an antibiotic and then she wanted to recheck. Had that done in April and his creatinine was 1.9.
She had me switch him to kidney food and said next steps were to recheck blood level in a month or pursue an ultrasound to check for tumor, stones, etc. Overall, I like the vet however I’m seeking a second opinion.
Additional background: He was treated for Lyme disease in 2024. He has not been on preventative since, but we stopped going hiking and we live in the suburbs. They did have us run that test again for some reason and of course it still showed positive. He does lick his junk a few times a day. Again, not sure if that’s normal or if I’m hyper focused on him.
I don’t have a lot of money (and that kidney food it expensive!!) but he is my sweet boy. What would be your next step?
