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 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.

This is my go to for healing my silver labs hot spots. The only product I have found that really works. Chewy's makes it easy by contacting your vet to confirm the prescription. My vet only has the small bottles that do not last so I order the large bottle through Chewy's.

It took about a week of daily applications, but the hot spot finally began to heal. The spot is on the back of his rear leg, and he has had it on and off for over a year. Glad to see it shrinking!

Fixing his paws right up

This stuff takes about 2-3 weeks to work. But it has really helped my boy enjoy his walks again and stopped his paws from breaking out.
