I have 2 cocker spaniels. Began using Pet Protector Discs on them 5/7/16. Last tick I found was 6/14/16. We live on the SouthCoast of MA and walk in the woods almost every day. The Disc lasts for 4 years. I will probably order new ones at 3.5 years to be safe. I feed raw, don't vaccinate any more (older dog is 9 yo, younger one 3.5 yo.), will titer and have heartworm blood tests done in Aug. and Nov.
