This afternoon, Sadie & Spencer had a nap on my bed. After they got up, I found a fully engorged tick on my bed. I could not believe it. We have had a mild winter, but it has been below freezing several times. However, obviously not long enough to kill all these suckers. Now, my concern is that Sadie & Spencer have been off their flea & tick prevention since about November. I intend to call the vet on Monday, but in the meantime, thought I'd ask what you all think. Ticks are not common in my area, and I have not found a tick on either of them in years, even in the warm weather. Do you think I should re-start their flea/tick prevention now? I still have some left.
