My beagle has a small rash on her inner front arms and a tiny bit between her front toes. It’s red and flaky a little and dark colored but doesn’t have an odor and she doesn’t seem to be in pain from it. Could it be contact dermatitis?

Thank you for using Petco Pet Education Center, formerly Petcoach! I can see that Rillie has some irritation and discoloration of the fur. The discoloration is from chronic licking, and saliva contains enzymes in it that cause the fur to change color. The areas she has been licking are typically areas that flare up in cases of allergies - these can be to something in the environment such as mold or dust, or certain proteins in food. While the itching is not comfortable, the chronic clicking causes destruction of the skin barrier and this predisposes Rillie to bacterial and/or fungal skin infections. Your vet can determine if an infection is present and perform bloodwork to rule in/out specific allergens. I hope this helps and am happy to answer any other questions you may have!

She has a red area on the inside of her leg near her private area. It almost looks like dried blood but it won’t wipe off, maybe a rash?
Thanks for using Boop by Petco! This is possibly due to allergies. It really comes down to figuring out what is causing her 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 envir

My dog has a rash in his right armpit and elbow. We took him to the vet and they weren't sure what could be causing it. They prescribed him Betafuse vet gel and told us to use it twice a day for 2 weeks. It's been 2 weeks now and the rash has gotten

Hello, my dog Raven has been itching for awhile. I have been giving her Zyrtec allergy medicine for 2 months but I’m not sure if that’s been helping. Just the past 4 days I have started giving her Salmon Fish Oil Omega 3 with Wild Alaskan Salmon Oil
Thank you for using Boop by Petco. From your picture it appears that Raven has a skin infection. This usually occurs secondary to allergies as they lick and scratch leaving the skin more susceptible to yeast and bacteria. I would recommend a vet visit to get her on appropriate antibiotics and possible a medication for allergies. There are many treatment options to try for an itchy dog.

What is this? How do I treat it? The dog’s skin is bright pink. Where all the gray spots are feel hard with matted fur and underneath this is irritated skin. It is only on the interior of one leg and in the under arm of that leg.
