Took Diego to the vet last night for a check up, shots and possible UTI. We were there for 2 hours, he had to be sedated, had urine/blood drawn and x-rays. He has a large stone in his bladder. No crystals associated with it so that's good. Due to the nature of it they need to remove it so this will happen tomorrow, Jan 27. They will send the stone out for testing to determine exactly what it is and how to move forward with food, meds, etc. I feel so badly for him, it has to be very uncomfortable. Would appreciate all the good thoughts we can get for my boy tomorrow.
