Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Yes, doxycycline is used to treat tick borne diseases. It seems as though the doxycycline is coated in a probiotic. I can't say I've seen this form in the US but it should be fine. Have a good day!

Doxy is the right medication, but he definitely needs to be on a tick prevention product like nexguard or advantix every year during tick season in your area to prevent further infestation by ticks.

Hello, thank you for using Pet Coach. I am so sorry for you loss. I know it is difficult to lose part of your family under any circumstances. I am not quite sure why you are wondering about doxycycline though. As you know, it is an antibiotic and is not indicated in treating lymphoma. Prednisone is the only treatment if chemotherapy cannot be instituted. Prednisone is not a curative medication, it only works to slow the growth of the cancer. Doxycycline does not do anything to treat cancer. If you can provide more information as to why you are referring to the doxycycline we can maybe help you better. Again, I am sorry for your loss. Best wishes.

I would recommend trying the antibiotic one more time. Make sure Chloe has a full stomach prior to giving it. If she vomits again, I would recommend calling your veterinarian tomorrow and discussing what the next steps are. Thank you for using Petco Pet Education Center, formerly Petcoach.

I would recommend putting dozer on a 30 day course of antibiotics before the 2nd and 3rd injection. I would recommend consulting your vet for the medication and the proper dose. The antibiotic will kill the bacteria that live in the mircofilaria and are though to cause more inflammation.
