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). Hope this answer was helpful, but 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. If this answer was helpful please let us know, this will be used to improve our service!

    Thank you for submitting your question regarding Huck. His skin looks very irritated. I recommend bathing him with a moisturizing shampoo and conditioner such as an oatmeal or fatty acid based formula to help soothe the skin. He will likely need to see his veterinarian though. There are many causes of rashes in dogs, but allergies are common this time of year. As humans, we inhale allergens such as grasses, weeds, pollens and molds. Dogs, on the other hand, walk through and lay in the grass. This causes inflammation of the skin on the belly. He may require antibiotics if there is a skin infection and possibly a medication to stop any associated itching. I hope this information helps!

    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). A buster collar would be useful to avoid further licking.
