Why is my dog's butt itchy and scabbed from chewing? What to do?
Poor Buddy! It sounds like this area is itchy for him. This itching can be caused by [fleas](https://www.petcoach.co/dog/condition/flea-infestation-1/), [mites](https://www.petcoach.co/dog/condition/mange/), [ringworm](https://www.petcoach.co/dog/condition/ringworm-1/), or [allergies](https://www.petcoach.co/dog/condition/canine-allergies/). If he isn't up to date on his [flea treatment](https://www.petcoach.co/article/how-do-i-pick-the-right-flea-and-tick-product-for-my-pet/), he will need a spot on treatment, such as Advantix, or a prescription oral flea preventive, such as Bravecto, Nexgard, Simparica, or Credelio. You will need to disinfect the environment as well. If he is up to date on his flea treatment, I recommend taking him into your vet for an exam. Your vet can do blood tests, skin scrapings, and use a Wood's lamp to diagnose allergies, mites, and ringworm. Once the cause of the itching is found, your vet can prescribe the appropriate treatment. I recommend taking him into the vet today or tomorrow. He will also likely need an [E-collar](https://www.petcoach.co/article/e-collars-for-cats-dogs-types-of-collars-and-diy-options/) (cone) to prevent him from biting at that area until he sees the vet.
