PetMeds® Causes of Your Dog’s Itchy Skin and Hair Loss (Hot Spots)

 
Filed under Dr. Dym's Vet Blog
If your dog has persistent hot spots, they should be examined by your veterinarian It happens all the time: One day your pet has a shiny coat full of luster and the next day there is a large patch of hair loss that is sensitive, moist and oozing. Sometimes the skin is sticky and this can cause your pet to be very uncomfortable. In worse cases, these sticky lesions can also be scratched until they bleed. This common sudden skin change in dogs is often referred to as a “hot spot” which refers to a sudden area of intense skin inflammation as described above.

These areas can emerge anywhere on a pet’s body, but most commonly are seen under the ears or skin folds of the neck, and often down the lower back or flank areas. The causes of these frustrating and often painful eruptions are usually allergy based; either flea bite allergy, inhalant/contact allergy, and/or food allergy. Obviously a thorough flea combing should be done to make sure there is no evidence of flea infestation or recent exposure to fleas. Such pets should be on a good flea preventative program using such products as Frontline Plus or Advantage, or a natural form of flea prevention for clients more holistically oriented. The most first line of treatment in such pets with hot spots is to soothe the skin both topically and through oral medication. Oral antihistamines such as diphenhydramine, chlorpheniramine or clemestine can help break the itch cycle, as well as cleaning the area with a dilute antibacterial soap, and then adequately drying.  Topical anti-inflammatories such as Be Soothed, Excel Hydrocortisone Spray and Miracle Mist Skin Spray can all potentially help in offering the pet relief.

In some cases it is necessary to see a veterinarian who will usually clip the hair from around the area to allow it to heal, and clean and dry the area thoroughly. On occasion it is necessary to sedate the pet, in order to properly treat very sensitive hot spots. If the eruption is severe, oral antibiotics are often prescribed such as Cephalexin and/or short courses of oral Prednisone or Temaril-P, until the lesions dry and heal. With time and patience, most pets are back to normal in a short period of time. In those pets that have repetitive hot spots, it is important to explore the various underlying allergic causes mentioned in this article to cure this tendency long term.

    This is usually due to inhalent/contact allergies to molds, grasses, trees, dander, housedust, pollens, etc or food allergens. Try antihistamine like benadryl at dose of one half to one mg per pound twice daily. Also consider using fatty acid added to meals like nordic naturals pet omega 3 fatty acid which may help when used long term. Consider DMG liquid as well as proanthozone from 1800petmeds.

    I’ve been told that this is due to an allergy of some type. I try to make sure that I do not contribute by making sure my dogs don’t walk thru carpet fresh or freshly shampooed carpets, or on mopped floors.

    Derpending on her size, (check with your vet for dose), Dogs CAN take Diphenhydramine anti-histamine for allergies.

    Check for fleas and/or make sure on good flea control. Also good be underlying inhalent/contact allergies and/or food allergies. You could try oral benadryl at dose of one mg per pound twice daily and adding a fatty acid to her meals such as super pure omega 3 from 1800petmeds.

  1. [...] Skin allergies are amongst the most frustrating health problems exhibited by both dogs and cats, and are likely the most common reason for veterinary visits outside of wellness exams.  Pets present with various manifestations of self trauma from licking, biting or scratching at themselves. Commonly affected areas include the lower back, feet, ears, chest and abdomen. However, any area of the body can be affected.  Many pets can develop secondary yeast or bacterial infections of the skin or ear canals, which often add to the discomfort.  [...]
