My dog bites, loses hair, has a red spot. Could it be fleas?

Updated On September 23rd, 2025

Pet's info: Dog | Siberian Husky | Female | unspayed | 45 lbs

My dog has been losing her in her tail and the back if her body bc she bites it, we were told it was fleas and that she bites it a lot. As I was brushing her I saw a red spot (the one in the picture) and i’m wondering if it is the fleas or if it is something else? Also, are the dogs fleas contagious to humans?

That lesion is likely related to both the fleas and the biting. Flea bites are extremely irritating and some dogs will chew until the skin in raw. I recommend to treat for fleas with a product like Nexgard and if she is itching this badly, get some apoquel from your veterinarian which will make her feel better. It will take 6 months to get rid of all the fleas. Best of luck and please feel free to post any additional questions.
