Nat,
I have 2 dogs and my vet has never told me about the Lyme vaccine. I of course never asked, two dogs, and 4 cats leaves little in the wallet for more vaccines.
I had Lyme disease two summers ago. I had to take the antibiotics for 2 weeks then another type for 4 more weeks because the first didn't take care of those little worm like spirochettes. I have some residual knee problems, like minor arthritis so I am lucky.
My friend Richie has had Lyme since 1998 and has had a very tough time. Lost his business in Stamford, had to retire and is now on permanant disability.
But I would not recommend the Lyme Vaccine for humans. I have heard that it cause long term Arthritis symptoms which could debilitate you down the line. THe chances of getting bitten by a tick are less than the chance of having the vaccine symptoms.
Check with your Dr about the animal vaccine. If it will cause arthritis in animals you may want to just try and check your dog more often for ticks if they are outside alot.
