Is dog urine unhealthy to smell?

So my dog has been really down and lethargic lately, I thought he was depressed until he urinated on my bed without even attempting to go outside, which is abnormal for him, I took him straight to the vet where they took his blood and urine tests and told me he has no acid in his urine and his pH levels aren t normal.

(In case you re wondering, I have him on antibiotics and other medications whilst awaiting a urine test to know whether if it s his bladder or kidneys)

Meanwhile I went home to clean his accident, which was a pretty intense smell, I washed sheet by sheet and the blankets they covered, I used every cleaning product and odor killer I had for the mattress (including a carpet cleaner to suck most of it up) and then flipped it.

(Am now saving for new mattress) Anyway I read that smelling the ammonia from animal urine is really unhealthy... should I be worried?
