My Red Nose Pitbull has red spots on her skin and hair loss. She itches herself a lot. Can you please help me with a diagnosis. Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Female | unspayed | 10 months and 27 days old

This is probably due to a severe allergy, although it could also be fleas, 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, pollins, dust etc etc). Some medications can be given by the vet in order to repair the skin lesions (steroids and antibiotics). Please do not hesitate to contact us again on the forum or by requesting a consultation (where you can post pictures ) if you have any more questions or to discuss it any further.

Thank you for submitting your question regarding Thunder. Has he been had skin scrapes performed to check for a mite called demodex? This is common in his breed. It can cause hair loss and red skin. Allergies are also common this time of year, but you want to be sure there is not another issue. If it is allergies, then I use medications such Cytopoint or Apoquel to control any itching to allow the skin to heal. I hope this information helps!

Itchiness and red spots 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 Grace with a high quality flea treatment such as advantage spot on, if it doesn't help - take her 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.
