My dog has a yellow, crusty, itchy wound with hair loss. What is it?

This sounds like it could be a hot spot or superficial bacterial skin infection. Most of the time hot spots are treated with antibiotics and sometimes some prescription topical medications. I'd recommend making an appointment with your veterinarian.

This looks like a focal area of infection, commonly referred to a hot spot. I would recommend taking Sophie to the vet to have the area clipped and cleaned. Sophie will probably need to be on antibiotics to help the skin heal properly.

From the crusting and redness, it does look like Lexi has an infection in her skin. You could start by doing a compress with warm wet washcloth to soften up and clean the crust away. Then clean the area with an antiseptic like betadine solution (diluted to the color of weak tea) and apply a topical triple antibiotic ointment. Based on where exactly it is, I would put on a cone or even a little t-shirt to stop her from scratching at it. If it doesn't improve or starts to spread, I would definitely recommend taking her to a vet for an exam as they sometimes need to be prescribed oral antibiotics.

It sounds like she has a hotspot which could be secondary to allergies and/or an infection. The best thing would be to have your vet take a look at it to determine the best way to treat. She may need an antibiotic, anti-histamine, and or a corticosteroid to treat and your vet can prescribe. If you can't take her to a vet than you could clean the area with an antiseptic wound cleaner but if she keeps scratching the area than it will not heal. Covering the area probably will not work but you could get an E-collar to prevent her from scratching.

It sounds like your dog has a skin infection so he should be examined by a vet to determine the exact cause. It could be secondary to an injury or possibly allergies. He may need an oral antibiotic and an anti-inflammatory to help treat the problem.

Hi! Its great you have a picture in there! So, the wound appearance is similar to a fungus infection, which is quite common in dogs with this type of fur as in golden retrievers. It's not easy to dry it completely, so some fungus can take advantage on that and cause an infection. As it is pruritic (a nice word for itching), and fungal infection in the majority is NOT itchy, a secondary bacterial contamination can be occurring. You will need some extra diagnostics work up with your vet to figure this out, or do an diagnostic by exclusion (treating the most common causes to see if helps). Other very important fact to be looked at, is if this "crusty - like" wound was caused by the itching problem and there is another underlying skin allergic reaction happening such as, flea allergy (remember you don't have to see the fleas on your dog for this), food related allergy, atopic allergy, etc. As I don't know for how long you have been treating Cody, so the antibiotic might no had kicked in yet. Cold baths with Chlorhexidine shampoos (you can even buy "Dettol" on supermarket) can give some quick relief.

It looks like your dog has a skin infection so he should be examined and treated by a vet. He, likely, needs an oral antibiotic and an anti-inflammatory that your vet can prescribe. If the meantime, you can bathe him with a medicated shampoo, like Douxo Chlorhexidine. You could also spray the lesion with Vetericyn wound and skin care spray.
