Unfortunately both lyme and erhlichia can cause an infection again, even after initial treatment. I would recommend treating her since she has clinical signs, but also ask your vet if they can run a PCR test to confirm active infection, rather than just exposure. That was you can be sure this infection isn't just from last year. I hope that helps. Thanks for using Petco Pet Education Center, formerly Petcoach!
