Yeah, I used to get my last dog the shot for it - but like the post above, I've heard it's not foolproof. But now that they have come out with Bravecto, which kills ticks within 12 hours of them biting (it takes minimum 24 hours of the tick being attached to transmit Lyme), I use that. I can tell you from experience with dozens of tick bits on my new dog this year that it works - we usually find them completely dried up and dead on her pillow. I'd suggest you ask your vet about this as an alternative or even as-well-as the vaccine. If you search around on gun dog forums etc...I think you'll find similarly positive reports from other dog owners who have tried it.
Cheers,
Dave
