My 11 year old dog Sprecher, has doggie colitis and has had 2 bladder stone surgeries! The vet has told me that of he were to need surgery for his stones one more time I’d have to put him down! The biggest problem is the food that can be eaten to avoid colitis can cause stones and to avoid stones it flares colitis! After 1 month of Canna advanced Maple-Bacon treats we are sleeping through the night and not having major flare ups! Even on bad days when he won’t eat the eggs and chicken I’ve made for him I know he will eat a biscuit! You have given my “puppy” more joy in both our lives!
