Why is my 8-week old puppy itching with scaly, yellow crust?

This sounds like an allergic reaction. first of all make sure you flea your puppy regularly every month with a high quality spot on (ex. Advantage) as fleas are by far the most common reason for these reactions. If the fleas are not the problem, it could be an allergic reaction to food or an environmental factor. this is more complicated to treat and will sometimes require medications such as antihistamines in order to stop the allergy.

This presentation 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, 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).

Scratching and crusty scabs can be caused by various reasons such as fleas, mites ,fungal infection, bacterial infection and allergies. the first 4 needs to be ruled out before we start treating for allergies. in order to do that first de-flea Leon with a high quality flea treatment such as advantage spot on, if it doesn't help - take him to the vet in order to check for/treat the other possibilities. If everything is ruled out, then an allergy treatment can be started. Usually an hypoallergenic food is a good way to start together with anti histamines. if it doesn't help - the best solution is a medication called Apoquel which treats allergies with great success and without side effects.

Any treatment will depend on the underlying cause. It could be a skin infection or allergic reaction or even an autoimmune condition. An exam with your veterinarian or a veterinary dermatologist would be needed for a definitive diagnosis. You can discuss allergy testing, hydrolyzed diets, food elimination trials as well as antihistamine use with your vet. In the meantime, if your dog is scratching, use an e-collar (cone) to prevent further trauma. Consider adding an essential fatty acid (EFA) supplement to the diet. EFAs can promote a healthy [skin and coat](https://www.petco.com/shop/en/petcostore/category/dog/dog-health-and-wellness/dog-vitamins/dog-skin-and-coat). Choose a good quality fish oil as a source of EFAs. Systemic or topical antibiotics or antifungals can treat bacterial or yeast infection. Allergies can be frustrating to diagnose since they have many causes. Once diagnosed, most allergies can be managed with a combination of medication and diet.

There are many possible causes of scaling skin and crusts, including skin infections from allergies (flea, food or environmental) and even some endocrine/metabolic conditions (hypothyroidism or Cushing's disease). If Xara is licking her paws excessively, this is a sign of itchiness. Since none of the lesions appear irritated, consider bathing her with a gentle dog oatmeal based shampoo and closely examine her for signs of fleas or flea dirt, which resembles a fleck of pepper. Make sure she is on a high quality flea preventative once a month (Nexgard, Bravecto, Advantix, Comfortis/Trifexis). Consider changing her diet to one with a different protein source, but do so gradually over 5-7 days. Diet changes can take 2-3 months to achieve efficacy. Obviously if her skin begins to look worse or does not improve with these measures, take her to her vet for an exam.
