Hello! My 9 year old Aussie/border collie/lab mix just got his second TPLO surgery last month and my vet has him On cosequin once daily and durlactin twice daily. He now has a recurring UTI and the vet keeps prescribing amoxicillin for him. He’s been cosequin for a year and just recently been out on the duralactin. Could the cosequin and duralactin together be doing damage to his kidneys?

I would be surprised if those tablets were doing and damage as they are supplements as opposed to nonsteroidal medications. However, in an older animal it would be wise to double check kidney function. Also in the case of a recurring infection I would advise submitting a urine sample for culture and sensitivity.
