Its possible. They can have ticks on the fur but they won't bite. We are extra careful because 2 of our dogs are allergic to the Lyme preventative shot. My yard being fenced in helps as other critters like deer can't come prancing in. I know tics hide in leaf matter but I do wonder if the lack of snow this year was in our favor. Next door neighbor has Guinea hens too and that's gotta help some.
