My puppy is chewing and scratching her legs and stomach. What's wrong?

Pet's info: Dog | Border Collie | Female | unspayed | 5 months old

For about 2 months my (now) 5 months old border collie pup has been chewing on her stomach, legs, rump and feet. It looks like she is trying to scratch herself. One of my friends has her sister and she is doing the same thing as well. What is this and what can I do?

Poor June! This scratching can be caused by fleas, mites, ringworm, or allergies. If she isn't up to date on her flea treatment, she will need a spot on treatment such as Advantage or Revolution. You will need to disinfect the environment as well. If she is up to date on her flea treatment, I recommend taking her into the vet for an exam today or tomorrow. The vet can do blood tests, skin scrapings, and use a Wood's lamp to diagnose allergies, mites, and ringworm. Once the cause of the scratching is found, the vet can prescribe the appropriate treatment.
