Review on Protecting Your Dog: Hartz 🐕 Ultraguard Plus Flea & Tick Dog Collar by Leo Torres

I spent about four dollars on two of these. I got them because my neighbors dog has fleas and ticks and my chihuahuas always get them no matter what we did. We've used tweezers to remove it and flea and tick shampoos, but nothing has helped in the long run. The necklaces have been on dogs for about a week now and they definitely have fewer fleas. You can tell the necklace is shedding a powder covering their fur, which isn't great (you can't see it but you CAN feel it) but they seem healthy and not irritated yet. I have followed the instructions and followed the directions on the packaging and have not used any other products right before the necklaces. I also left the necklaces loose enough so they wouldn't fall off and so far so good!
