There are a number of medical causes of itchniness in a dog, including ectoparasites, infections of the skin (fungal, bacterial, viral), metabolic disorders, and even allergies. Sometimes allergies are to ingredients in the dog's food; sometimes they are due to irritants in the enviroment, like fabric freshners, laundry detergents, floor and carpet cleaning products. You should have your dog evaluated by your veterinarian. S/he will want to do a complete physical exam and may also recommend taking skin/hair samples for diagnostics purposes.

If the area is inflamed enough to the point that it smells and is oozing debris, it is very likely an infection like you suspect. This needs to be seen and treated by a veterinarian as antibiotics or other medicated prescriptions shampoos will need to be used to treat it. Until you can get to your vet, keeping the area clean and dry and using an Elizabethan (cone) collar to keep Shadow from scratching can help, but it needs to be seen in person.

Alone that abnormality isn't concerning at all. It does mean his red blood cells are a little less dark than expected, but with a normal red blood cell count it isn't something significant. As far as the itching, that can be caused by allergies to food, fleas, or the environment, or infections (bacteria, yeast, parasites), or other issues with how the skin is formed. If this allergy test was normal (and all infections have been ruled out), I would talk to your vet about hypoallergenic food trial.

Hi, and thanks for your question. This could be 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).
