Puppy has mange symptoms: hair loss, eye issues. Is it serious? OTC help?

I think my puppy has demodectic mange. He's about 4 months old. Around his eye is usually wet. He has lost hair around one of his eyes and some on the top of his head. His eye is getting kind of swollen and looks like it's getting red. I feel so bad for him but I was just laid off and can't get him to a vet. Will this go away on its own? Is there something I can get at Tractor Supply? Is this the same mange that kills dogs?

Hi and thanks for your post. Demodex mite infection can be occur in younger dogs and may spontaneously resolve as their immune system becomes more mature. Demodex mange is not typically itchy but sarcoptic mange is. The area of hair loss around the eye in the picture does look suspicious of demodex mange but you will want to get this confirmed with your veterinarian first. A skin test in needed to accurately diagnosis demodex manage in dogs. If it is demodex, unfortunately, there is nothing over the counter at tractor supply you can purchase for this. You veterinarian may give you a prescription medication for the mange if necessary. Either types of manage (demodex or sarcoptic) typically is not fatal unless there is a more serious underlying condition at play. Both types are treatable.
