Why does my senior dog's tick fever keep coming back after treatment?

An anti tick collar prevents tick infestation and kill fleas. tick fever and babaesia canis are two different things although they often come together, tick fever can become chronic, in this case the infection may not be completely eradicated and your dog might suffer from it again.

She could still be suffering from Tick fever, this disease is known to be very resistant to treatment and it sometimes takes several months of treatment to get rid of it. you will need to take her back to the vet ASAP in order to resume the antibiotic treatment, this time for a longer period of time.

Your dog has a blood parasite transmitted by ticks, ie Babesiosis. Up to now, no single drug has effectively and consistently eliminated B. gibsoni from infected dogs and the side effects, as well as availability, of some of the medications limit their use. Here is information on B.gibsoni infection. You may want to discuss with your veterinarian, whwther he wants to proceed with treatment or just use supportive treatment. There is no virus involved. http://www.vetfolio.com/infectious-disease/babesia-gibsoni-an-emerging-pathogen-in-dogs

Thank you for using Petco Pet Education Center, formerly Petcoach! Itis good that Bruno is feeling better. Babesia gibsoni can be very hard to completely clear and is an infection that can remain in hiding/dormant with no outward clinical signs. Therapy with variety of different medications has been tried with varying success. Months (2-3) of therapy is often needed. It is important that control of the vector (ticks) be a priority in preventing reinfection if the current infection is cleared.

Hi and thanks for posting! If Bruno was diagnosed with a tick borne illness by his veterinarian, the fever he experienced may be due to this. If he was placed on any inflammatory medications, this would have helped his fever subside. There are many other medical causes of fever in dogs aside from tick borne diseases which should be explored and ruled out with Bruno's veterinarian. I hope this helps and thanks for using Petco Pet Education Center, formerly Petcoach!

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!

Best take him to a veterinarian tomorrow as he will need a blood test and medication for about 3-4 weeks again against the babesia. There is nothing you can do tonight until you take him to the vet. He should be fine. Should his temperature go to 40C or above you need to take him to a vet tonight, either an out of hours service or a pet ER.
