I use Frontline Plus on Columbo & have for the last couple years. Didn't need anything for years and then all of a sudden the tick population exploded, so I started using it. Sams Club definitely has the best price. About $38 for a 3 pack. I also find Columbo only needs a treatment about every other month. I have seen ticks on him at around the 7 or 8 week mark, so I don't go beyond that. Fleas have never been a problem for us. He is 8 lbs. |
