Diagnosing & Treating a Dog Skin Rash & Dog Skin Allergies

Dog skin allergies or a dog skin rash can present themselves at random times for no particular reason. 

Humans deal with skin issues constantly, and we have thousands of creams, rubs and medications to eliminate the issues. There are many serious skin issues that our dogs can become afflicted with as well, but because of their thick coats, it’s slightly more difficult to diagnose the exact skin problem.

Let's dive into the details...

Dog Skin Rash & Allergy Symptoms

A simple dog skin rash is comparable to a human skin rash in these ways:

  • We’re not always sure why it’s there
  • It can pop up on the skin within a matter of seconds
  • It can be very itchy and obnoxious
  • It can be cured quite easily with the right treatment

First, take a close look at the area you have noted to be a possible rash on your dog’s skin...


Does your dog apear to have pimples? Acne may be the culprit.

See our Canine Acne page to determine whether your pooch has pimple problems and to learn how to treat them naturally at home.

  • Does it look red, flakey and/or slightly swollen?
  • Has your dog been scratching it with his paws or nibbling on it with his teeth?
  • Did it just pop up within the last few hours without any sign of additional symptoms?

If you answered 'yes' to these questions, the chances are quite good that your dog is dealing with a rash. 

The following symptoms are also sometimes present:

What Causes a Dog Skin Rash?

Dog skin rashes have several instigators. Click these links for more details about each:

Drug allergies may also be the cause. If your dog is taking medication, call your vet and ask whether it is safe to take them off for a few days so you can find out whether the drug is causing the problem. 

Finally, the rash could be caused by an injury to your dog's skin.

For more details about each of the above causes, see our Dog Skin Conditions page.

Natural Treatments for a Dog Skin Rash

If you are looking to provide your dog with some instant relief, here are a few natural remedies that will soothe the inflamed skin and reduce some of the itching:

dog skin rash
  • Natural Skin Salve/Spray - Many natural ingredients exist that are very effective at healing skin rashes or hot spots and calming skin irritation and discomfort including shea butter, tea tree oil, rosemary, sesame oil and aloe vera, among others. A good option to try that includes some of these is the DERMagic Cell Restoration Creme.
  • Coconut oil - severe skin dryness and itchiness may be alleviated by some coconut oil soaks one time per week. Massage in some coconut oil (Nutiva's Organic Coconut Oil is a good option) all over the areas that are dry and scaly and let it soak in for 4 to 6 hours. If your dog is still greasy after 4 to 6 hours, shampoo him with Palmolive dish soap to remove the excess oil. If the oil has all soaked into his skin, use a baby shampoo.
  • Aloe Vera cream or gel - Aloe is natural healer that is used to treat various skin issues on humans and animals alike.  You can apply the aloe to the irritated skin either directly from the plant or in a gel/lotion form sold in stores.
  • Milk of Magnesia - this soothing substance has been found to benefit itchy, dry and irritated skin.  Just pour a little onto a cotton ball and apply to the skin of your dog.

  • Oatmeal Shampoo - Tropiclean Oatmeal Shampoo is great for dogs prone to skin rashes and goes a long way toward releif from itching.
  • Baking Soda - Mixing baking soda with water and applying it to the skin of your dog may provide much needed quick relief from itching. 
  • Apple cider vinegar is sometimes useful in the skin fold areas under the neck, armpits and groin if there is any yeast or fungus associated with the formation of 'elephant' skin. You can apply it two to three times per week with a wash cloth to the affected areas. See our Benefits of Apple Cider Vinegar page for more information.
  • Consider alternative medicine for dogs to avoid the negative side-effects of medication – skin rashes are only a minor side-effect among many more that are longer term and more severe.

Remember: Keep your dog from intense scratching, licking or biting of the skin spot.  This could cause bleeding and possibly infection, so don’t wait to provide some relief!
