Is Quercetin safe for dogs with bladder crystals and allergies?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Female | spayed | 6 years and 3 months old | 16 lbs

My yorkie mix is on urinary so diet for bladder crystals (struvite and one other kind) with excellent control. She is currently taking chlorpheniramine maleate for vet diagnosed environmental allergies which works but I want to switch to a natural product. I'm wondering if it would be OK to give Quercetin to a dog bladder crystal history. She has never had kidney problems. I would be giving it with bromelain/papain and possibly omega 3. She also takes Natural Pet Only Urinary Control tabs.

Quercetin is probably safe, however, there is not evidence (in animals or people) that it helps for either allergies or urinary health. Papain/bromelain are good choices as they both do have evidence to support anti-inflammatory and possible immune modulating effects. Omega 3’s are another of my go-to’s for allergies. All of that said, I have not had much success with moderate to severe allergies without western medical choices (but with mild allergies it can work!). Hope this helps and best of luck to you and Blessibg!
