My bulldog has been battling ear issues due to allergies for a while now. A cytology was done by her vet and these drops were determined to be the best to clear up her ear. I saw immediate improvement in just a few days. Only down side was the delivery. The first shipment arrived outside the advised date due to being a cold product. But Chewy was awesome and took notice of that fact before I did and sent a replacement. So I did have to wait longer but the product itself works very well.

Chewy emailed me stating they received the prescription. In that email it showed the prescription showing 3 refills ! When I called to get the first refill the customer service agent insisted I had to call the vet to get the script sent in again. I explained that I received the email from chewy with the script showing 3 refills. He refused to let me speak to his boss. So unfortunately I called the vet and they re sent it. Why chewy why ??? Por customer service !

My Chloe has allergies and I needed to refill a prescription so that weather would not hamper treatment if I couldn’t get out to the vet. This medicine has to be kept cold. This tiny little bottle was wrapped up securely within a cold pack, then packaged within another temp controlled package, then within another cooler box. So impressive. On top of that, it was delivered within 1 day! Great job, Chewy!

Chewy is a reliable and trustworthy shop

Imagine when your medication is the size of half of your finger, and you received a GIANT package with triple ice packed and wrapped to fully protect inside, you know you’re in good hands! The medication my doctor’s office gave me is room temperatured and that’s why it’s not showing any effectiveness. I will use this one instead to see if it can make a change.

Smooth purchase

These are drops Lucy has used for years for chronic ear issues. They work great, it’s an on going treatment. The order came quickly, packed well in many ice packs and the prescription request was approved fast. The only issue is the expiration date is very short, less than 5 months, where when purchasing from my vet it is good more than a year. We never run out, it gets old first. At 5 months I’ll be throwing away a pretty full bottle . They said it was a new batch from the manufacturer. I think they should check things like dates and question the supplier. They did give me a $20 credit which I appreciate but I’ll need to order a new bottle in 4 months.

Great packaging and fast delivery

I loved how well the medicine was packaged. It was cold as it was supposed to be transported and kept. Very well packed to absorb any shock. And it was delivered

This stuff helps my dogs hot spots heal so well. Within a few days of using he's no longer itching and the redness is gone. It takes a while for the spots to dissipate,
