Why does my dog keep getting hookworms and have persistent itchy skin?

Updated On September 23rd, 2025

Pet's info: Dog | American Pit Bull Terrier | Female | unspayed | 1 year and 1 month old | 40 lbs

Well for starters i'll explain that Sugars had a problem with hookworms since she was younger. I took her to the vet and spent alot of money to fix the problem. But it seems to keep coming back. Her skin and hair are itcky. The itching persists, the fatigue, and even rubbing continuing after numerous times of deworming every few weeks. Ive tried to even buy a better dog food. Why does she keep getting hook worms?

Hookworms are present in the environment so Sugar may be getting constantly reinfected. The best way to prevent this is to have her on a monthly heartworm prevention (like Heartgard or Trifexis). This will protect Sugar from heartworm disease and intestinal parasites as well. However, the problems you describe Sugar as having sounds more like skin allergy issues rather than a problem with worms. You may want to post another question or request a consult so we can try to help you get to the bottom of Sugar’s problems. Best of luck!
