The medication is working well to clear up my senior dog’s skin condition.

I want to say a big thank you to Chewy for providing us with exceptional service. I am a new customer to Chewy. The pharmacy contacted me as soon as they received

I want to say a big thank you to Chewy for providing us with exceptional service. I am a new customer to Chewy. The pharmacy contacted me as soon as they received the prescription. Unfortunately, the shipping company sent the package to Tennessee where it sat for almost a week. I contacted Chewy and a replacement bottle was sent out within a day. A representative from Chewy contacted me to ensure that the medication was delivered. Everyone I dealt with was kind, responsive and knowledgeable.

Ringo as he aged has developed some skin issues. When he reached 12 he developed skin sores, yeasty smell. They come off but they come back. I was brushing them off and ended up scraping off his skin. It’ll heal but those crusty, eczema looking, yeasty smelling sores would come back. Did chlorhexidine foam, did not work. Did a lot of chlorhexidine baths, helped a little bit but the sores never went away. He was itching. Licking himself and I knew he wasn’t comfortable. I’m glad I found this and my vet signed off the prescription.

This product is the best at controlling the skin irritation associated with my boys itching and allergies. It does sting a little bit on open sores but it’s the only thing that seems to keep the out breaks under control.

My Pom got a small scabby ring on his butt and his fur within the ring fell out. Within a week it spread significantly. My vet gave him another spray but did not help. Then he prescribed Gentamicin and within days got rid of the infection.

Best stuff ever

Beats the expensive Apoquel (sp) in taking care of a rash both dogs will get between their legs. Best solution ever. Cannot recommend it enough.

Best topical spray for raw canine skin

This product is a miracle drug for us - when Buddy’s skin gets itchy and irritated, esp his feet after chewing them, it helps heal the raw area quickly.

Lack of medication for the price

I believe that the bottle I received was not adequately full, it was about 3/4 of being completely full, very unsatisfied.
