My dog got tick fever. Can they get it again? How do I prevent it?
Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. Not all ticks carry the bacteria that leads to tick fever, so it is likely because a tick with tick fever has not bitten your dog yet. Unfortunately, once dogs get an infection, they do not develop long term immunity and can get the infection again. To protect a dog from getting tick fever, it is recommended to have the dog on a flea / tick preventative such as Frontline, Bravecto, Nexgard or Simparica. I prefer to use the Nexgard or Bravecto as I've seen the best results with both products for preventing ticks and fleas. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further. Please take the time to mark this question as helpful or not as it helps us to improve on the quality of our answers to other pet owners. Thank you kindly!
