My dog has a red circle spot with fur loss on her leg. What is it?

This could be ringworm or a hotspot. It doesn't look like it's cancerous to me, but I can't say that for certain without seeing Amber in person. Have her seen by a vet Monday morning to have this diagnosed and treated. Best of luck.

This is probably due to a severe allergy, although it could also be fleas or mites. First of all, in order to rule out skin parasites, you will need to treat Mia with a high quality flea treatment (e.g. Trifexis or Advantage), then get her to the vet to perform a skin scrape - this might reveal an infection or a mite infestation. If all of those came back negative, the next step is to treat the allergy symptomatically and try discovering the cause of the allergy. Some medications can be given by the vet in order to repair the skin lesions (steroids and antibiotics). simultaneously you should start her on a prescription hypoallergenic diet for at least 2 months. Hopefully you will see some results after all this, if not you and your vet should consider putting her on a long term allergy treatment (Atopica or Apoquel).

That spot on Buddy could be several things including allergies, skin mites, ringworm (which humans can get) or a bacterial infection. You can try adding in an omega 3 fatty acid supplement for dogs, this can help improve the skin health. You may also try changing his diet to something like Royal Canin or Nutro as they are aimed at skin health. You can wash the lesion with soap once a day and rinse well (don't wash his whole body, just the spot). Protect the area from licking or scratching. If it doesn't start looking better within about a week or if they get worse, have him examined by the veterinarian who may prescribe medications. Best of luck and please feel free to post any additional questions.

It's possible that Feli has been licking or scratching this area, causing these abrasions. This type of lesion can develop pretty quickly - even overnight. Some of the most common causes of itching include allergies and fleas. Make sure that she's regularly receiving a good quality flea preventive (Bravecto, Nexgard, Credelio and Simparica are all great prescription options, and K9 Advantix II is available over the counter). You can also give her a bath in a gentle oatmeal or baby shampoo in case there are any lingering allergens on her coat causing irritation. You certainly don't need to rush her to a vet for these lesions alone, but if they get worse or spread, then you should take her to get checked out. When dogs scratch, they can damage the protective skin barrier, which can make them susceptible to developing skin infections. I hope that she's on the mend soon!

Bo's lesion looks most suspicious for a bacterial skin infection, but could also be due to ringworm, mange, or bruising. Since it does not seem to be bothering him, you can monitor the lesion for the time being to see if it changes colors, grows, becomes itchy, or spreads elsewhere. You can also try bathing him with an antimicrobial shampoo (here is one example: http://www.drsfostersmith.com/product/prod_display.cfm?pcatid=27982 ). However, if the lesion worsens or seems to be causing discomfort, it is worth taking a trip to the vet for evaluation. I hope that all goes well!

When I hear that a dog has red circles on their body, my first thought is ringworm. This is a highly contagious fungal infection that can spread to other animals and humans as well. It could also be that Sophia has a skin infection or may have injured herself leading to these red circles. The only way to know for sure is to have her seen by a vet, and I recommend taking her in today or tomorrow. The vet can diagnose what is causing them and how best to treat them. If she does have ringworm, you will need to disinfect the environment because the spores can live in it for up to 18 months. I can give you a link to a website on how to do this: http://www.livestrong.com/article/49666-rid-home-ringworm/

It looks like Ruby has an abrasion to the skin. She has likely been jumping up and rubbed the inside of her leg against something, the friction causes the injury to the skin. It is quite superficial so should heal by itself. You can clean it with salt water if you wish. A little bit of antisceptic cream can help settle such wounds.
