Itchy dry skin

Hello Bassett community, my Hank suffers from some bad skin allergies all year round it feels like. He’s been getting cyto injections from the vet. But I’d say about a month ago. His skin is just so dry everywhere, does anybody else’s basset hound get ultra dry red skin? If you do, what do you use to combat it?

I always joke around that he’s allergic to grass 😂. Leave me alone.
