What's causing my dog's strange hair loss and suspected allergies?

Updated On September 23rd, 2025

Pet's info: Dog | Pembroke Welsh Corgi | Female | spayed | 7 years and 9 months old | 30 lbs

My corgi named zoey has been loosing hair for a while, in a very odd way. She resembles a cheetah right now. I shaved her down. To get a better look at these damage. I suspect it may be allergies so I switched to a salmon, pea and sweet potato dry food. She used to use Iams senior dry dog food, but I was sick of the hair loss. She had waxy ears almost yellowish, but I used home remedies and that cleared up almost instantly. I am desperate for some advise on what's wrong with her. Please HELP!!!

This is probably due to an allergy, although it could also be infection or mites. First of all, in order to rule out skin parasites, you will need to treat with a high quality flea treatment (advocate or advantage), then ask 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 to discover the cause of the allergy. Three main type of allergies are usually affecting pets: food allergies, flea and parasite related ones and environmental type (allergens coming from trees, pollens, dust etc etc). Some medications can be given by the vet in order to repair any possible skin lesions (like steroids and antibiotics). 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.
