This is the ONLY collar that really works on ticks. My dogs haven't had a tick since I put the collars on.

I live on 40 acres of wooded land and have seven dogs. I have tried everything on the market for fleas and ticks. Preventic collars are the best I have ever used. My dogs will run the woods and come back free of everything, not even a seed tick. If a tick should make it's way on one of the dogs, within minutes it will drop off. I know when it's time to put new collars on because the dogs will start to scratch and become uncomfortable. When they see their new collars they all wait in line.

Being a dog rescuer living in Miami, FL nothing eradicates ticks from the environment. We have a tropical, moist climate year round. Most dogs get ehrlichia here from ticks even with topical flea/tick preventatives. Ehrlichia will kill a dog if not treated and it often goes unnoticed. (I swear by annual or bi-annual HW/ehrlichia + other tick disease snap tests.) Preventic collars last 3-months and the 9% amitraz is tick specific. I find the collars well worth the small investment and I put the savings toward an oral flea med like Comfortis (unfortunately not sold yet on Revival's website.) Vets sell the same collar for as much as $25/each, so Revival's cost is extremely cost effective. Since using Preventic collars I've not seen 1-tick on any of my 4 dogs or fosters (of which there are many!) THIS PRODUCT IS WORTH ITS WEIGHT IN GOLD in protecting your dog's life.
