My vet just told me to give her over the counter meds but she obviously doesn't like the bubblegum and cherry flavors. But apparently I need a prescription to get pet flavor

Helps with the seasonal Itcheys

My dog has sensitive skin and puts up a real fight when giving her pills to ease her chewing drive on her skin. I am happy with the service by Chewy staff in helping me put this order through to my vet. The med is compounded with oil and chicken flavor, which makes it a bit easier to get down her throat.

For the dog who won’t take pills

Liquid benadyl makes getting medicine to Gingerbread so much easier. 3 different flavors also great. Thx chewy

We love this, our pup loves it too. She’s been prescribed Benadryl twice a day & refuses any inkling of pills in her food to the point that she’ll refuse food for days if she even suspects we’ve hidden something. She’ll lick this off a plate!

Pharmacy Flavors

My Tucker loves the Marshmallow flavor meds he's one that will not take meds. Vet gave chicken and beef flavor he hated it. He wouldn't take his meds at all ! Not until I ordered from here! Please always offer marshmallow!

Cat hates it

Bought this in hopes that it would help my Bengal with his current skin allergy and when I say he will fight me to avoid it, I mean it. Lol. It tastes disgusting and he sure shows the hate for it. Was curious why he disliked it so I tasted a tiny bit of it and omg I don’t blame him for running away when he sees the bottle. I bought Liquid Vet a while back and he’s ok taking that so it’s what I’ll stick with.

Cat won't eat it

I don't know if it works, because my cat won't eat it. The whole point behind getting flavored medicine is avoiding the stress and hassle of a fight to get the medicine into the cat. I got the 30mg version. Maybe the 10 mg would have been better received but I wouldn't hold my breath on that. It was also a royal pain to get Chewy to notice that the vet had approved the prescription.

Mother of Dog

I love this coat and I have purchased it multiple times as my little guy grew from a puppy to a big puppy. Despite the issues I’ve had with this coat, I would still recommended it. It’s adorable and adorable. Now I have had minor issues in the past with the seams. But unfortunately one of the straps that wrap around the stomach has completely torn off of his newest coat (XXX-Large). Very sad. Very frustrating. Still recommend.

Med is great but the syringe sucks!

The medicine itself is helping with the itching but that syringe is HORRIBLE! It sticks, you cant pull it apart and it’s just very hard to work with. I bought another syringe and things are much better.
