What is this red, raised, scabbed spot on my allergic dog's leg?

Thanks for using Petco Pet Education Center, formerly Petcoach! I agree that this is likely due to allergies. It really comes down to figuring out what is causing his allergies so that they can be treated or the specific allergen avoided. A secondary infection is likely and also needs to be addressed. There are many things that can cause allergies though in most cases they can be broken down into 3 big categories: flea, food and environmental allergies. Allergies are usually worked up in a stepwise fashion starting with flea allergies as this is the easiest and cheapest to take care of. If not on a flea preventative, then it would be a good idea to get started on one. If already on one then it would be a good idea to change to something else (there are many new products out in the market). If not improved in 1-3 months then it is time to move on and check for food allergies by switching to a novel diet (new protein and new carbohydrate). If that does not seem to be the issue then you are left out having to check for environmental allergies which require blood and/or skin tests. Allergies can be very frustrating to deal with at first but so rewarding at the end when we are able to treat them effectively!

This presentation could be due to a trauma or localized spot of skin infection (likely to be caused by bacteria). A check up, appropriate disinfection and possibly antibiotics (oral, topical or in a shampoo formulation) are needed to solve the problem. Disinfection may be started at home with very diluted hibiscrub or betadine or salted water baths. Buster collar may be useful as well to avoid any licking. Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

That spot on Baby could be several things including allergies, skin mites, flea bites, ringworm (which humans can get) or a bacterial infection. With the description of swelling, I recommend to have her examined. She likely needs antibiotics. At home, a few things that may help maintain healthy skin are adding in an omega 3 fatty acid supplement for dogs. You may also try changing her diet to something like Royal Canin or Nutro as they are aimed at skin health. Protect the area from licking or scratching, she may need to wear an elizabethan collar. Best of luck and please feel free to post any additional questions.

This looks like an area of skin infection. The smaller two bumps are pustules and the larger area is a pustule that has ruptured. Sometimes, if confined to a small area, these can be treated with topical antibacterial medication. If, however, it is more widespread your dog may need oral antibiotics. I hope this helps. If you have any other questions please let us know!

It could be an allergy or an infection. Hard to say without an exam and some testing. You can try using this medicated spray on the affected area . If after a week or so of treating her the skin doesn't look much better then she should see a vet. You would use one spray every day to every other day until the lesions have resolved.

You will need to take your dog to a veterinarian for a skin exam. Your dog could be suffering from an allergy, mites, fleas, a bacterial or fungal infection. each of these requires a different treatment, so it is important to find out what is causing the itch. This does, however look like a bacterial infection, Your vet will do a thorough exam and maybe a a skin scrape. He will then discuss the options with you and then prescribe medications such as antibiotics and possibly an antibiotic/antifungal shampoo.
