What's this rash on my dog's inner thighs? Fleas, mange, or allergies?

Question

Hi .. I am not sure what this rash is on my dog . We had a flea issue which has gotten a lot better . He is always scratching and biting. The rash is on his inner thighs and under armpits , a little on his stomach . I found a “hotspot” on the out side of his thigh that he was biting at.. I noticed that it looks much better after I give him a bath . I was concerned that it might be mange instead of flea dermatitis. I was hoping there was something you could help me with before going to the vet. Pet's info: Dog | Mixed Breed Large (61lb +) | Male | neutered | 70 lbs

Unfortunately, you can’t tell the cause of the rash just by looks alone. It’s possible this is still related to the fleas in the environment or that this is an allergic reaction. This could be a mange as well. I recommend to treat him with a good flea product like Simparica. If you must use an over-the-counter product, use Frontline. This is still a good product but there are some resistance with fleas. Make sure to protect the area from any licking or scratching with an Elizabethan collar. You can wash the area once a day and rinse it well. Start him on an omega-3 fatty acid supplement. If this does not start to look better within a week or if it starts to get worse, have him examined by the veterinarian. I hope this helps and please feel free to post any additional questions.
