Try the search engine here, under sign in, upper right, type in “calcium oxalate” or bladder stones”
From a previous post:
Increasing water intake helps with all types of bladder stones, frequent bathroom breaks, opportunities to urinate. Keep the bladder flushed. Stagnant conditions in the bladder are conducive to stone formation.
Maybe 3 small meals per day with water added, they just lap it up to get to the food. In fact, I would also pre-soak the kibble overnight in the fridg.
Increase activity, walks, reduce weight (if overweight).
For stubborn cases like your dogs, there are prescription medications the vet may recommend. I might consider consulting a Veterinary Internal Medicine Specialist.
