My dog has red, painful skin on his legs and paws. What should I do?

From the pictures, the skin appears red and inflamed. It does look like it is infected. While this may not be a true emergency, I would recommend getting in to see your veterinarian very soon. Pookie will need the area shaved and cleaned up. Your vet may prescribe an antibiotic for this as well depending. Until you can get to your vet, you can keep the area clean and dry and use a mild soap and water to clean the wound. If Pookie is licking it, you can put on ECollar on her to prevent licking.

These look to be inflamed and irritated not infected so antibiotics are unlikely to cure and may make the condition worse if the underlying cause is not addressed. Allergies, mites and yeast overgrowth would be quite common and I recommend a vet check to determine the best possible action

Treatment will greatly depend on the cause, however that looks like a hot spot. It should be seen by your vet, so they can clean it and provide you with some antibiotics and pain meds as needed. Until you can get to your vet, placing an Elizabethan (cone) collar on Hector to stop him from licking and worsening it, and keeping the area clean and dry can help, however if it continues to worsen it needs to be seen right away.

This is likely to be due to an infective pododermatitis. It is possible that the generalized infection is actually due to an underlying predisposing allergy. Three main type of allergies are usually affecting pets: food allergies, flea and parasite related ones and environmental type (allergens coming from trees, pollens, dust etc etc). Some medications can be given by the vet in order to repair any possible skin lesions (like steroids and antibiotics). The following products can be found online and can be tried as a first line approach: Douxo PS Calm shampoo, Essential 6 spot on by dermoscent, Krillex Krill oil chews.

This looks like a skin infection, you will need to take him to the vet ASAP, the fur in that area will need to be shaved and he will need to get a course of antibiotics in order to have this treated.

It looks a little red and inflamed so it could be an infection. You could soak his paw in a warm Epsom salt solution and see if that helps. Otherwise, have your vet take a look at him as he may need an antibiotic to treat the infection.

It looks like she could have a skin infection and/or an allergic dermatitis. You could clean the area with a wound wash and see if it continues to improve. Otherwise, she should be examined by a vet for treatment. She may need an antibiotic, antihistamine, or a corticosteroid to help treat.
