I Live in an tick infested area. Never picked a tick off the dog last year. Wished they made these for people.
Best flea/rock collars on the market. No smell whatsoever. I buy them every year in February for my two mini Australian Shepherds and they do the trick for the whole year. They each weigh 20 pounds and I buy the small dog ones. We have ticks very bad here and we will occasionally find a dead one on the dogs or sometimes a live one that just got there - but never ones that have attached.
I have been battling fleas for quite a while, using top of the line spot on product, spraying the house, bombed the house. I finally bought these collars and bombed the house again. No fleas! 2 weeks in extremely satisfied.
Six months ago I chose this as the flea protection for my blue heeler, it impressed me so well I discussed it with my vet and with his seal of approval on this product(he says they love them as well), I'm now back to choose this as my flea and tick protection for my seven pound toy poodle. No more internal monthly chemicals - Goodbye NexGard! My heeler has literally been 100% flea and tick free ALL spring, summer, and fall and this collar is still going strong. LOVE LOVE LOVE these! EDIT >> just to clarify I first purchased the large dog version of the product and upon return I purchased the small dog version.
These collars are terrific! I have two indoor cats and one indoor/outdoor dog. I've had issues where the dog brings in a flea and then the cats get worms. I hated putting on the ointment on their necks, so I gave these collars a try. I am so glad I did. We have had zero flea issues and I don't have to worry that they will get sick from licking off their medicine! These definitely last the 8 months that they say. I typically purchase them a few months before Summer - that way that start working in time and they are far cheaper than when they are more in demand!
