Quercetin works very well in helping my dog's allergies stay under control. Price was reasonable per others I have looked at. And she does not mind it sprinkled over her food so easy to administer. No after effects, just less scratching. Order was not delivered and refund is on its way. I will be reordering.

My beagle has severe seasonal allergies. He normally takes benadryl when they're uncontrollable, but long term use isn't good for dogs (or people). Supplements sold everywhere and chews that claim to help allergies and immune system etc.,don't work for him. I tried products advertised on social media and others sold at Petsmart, here at Amazon, etc. I've tried at least 10-12 dog chew type supplements on him. This quercetin and bromelain supplement has done wonders for him. It worked within a day. He's had 100% improvement after a couple of days. When the bottle finally ran out and he went without it for almost a week, he was miserable. So I bought another. I think it's pricey, however there are 120 tablets in a bottle, so if you don't have a huge dog, they should last a while. I wish it were cheaper, but his comfort is important and it works. I will continue purchasing. He chews it just fine without issue like a treat and they aren't huge tablets. His behavior and mood also improved, but I should assume it's because he feels so much better and he does. :)

After about 2 weeks his scratching stopped. My only complaint is so many of the pills come broken. They need to use a smaller bottle or put some cotton in.

Was not effective at all. Wished I could’ve returned it.

Since taking this for the past month my dogs skin has improved so much. I will definitely order again.
