Why is my dog biting her back, scratching, coughing, and vomiting?

Updated On September 23rd, 2025

Pet's info: Dog | American Pit Bull Terrier | Female | unspayed | 64 lbs

My dog constantly bites at her back right above her tail and now it’s red. Also she frequently has these coughing/ clearing her thoart fits which can lead to vomiting at times. She also scratches herself a lot. What do these actions mean?? Does she have allergies?

This would be a typical spot for fleas to bite and congregate, so if you have not done any flea protection you will need to start with that now. There is a possibility that your dog is suffering from a flea bite allergy, and getting rid of the fleas will alleviate that. The coughing fits/vomiting will need to be investigated by a veterinarian. This could be caused by kennel cough or another upper respiratory infection or a heart condition. I suggest you schedule an appointment with your veterinarian for an exam.
