My sister's dog tested positive for Lyme disease about a month ago. She's on doxy and they are going to retest her after the round of antibiotics are done. The vet said that they should give the Lyme vaccination at the next appointment anyway though - Meg wasn't very clear on why and I don't understand the reasoning. What good does it do to give a vaccination for something the dog already has? That seems like the opposite of the point of a vax. Sorry this is brief, I'm on my phone but have a picture of Pixie and Buddy in advance thanks.
