4 Pack Flea Collar for Dogs, Dog Flea and Tick Collar 32 Months Flea and Tick Treatment for Dog, Waterproof Adjustable Dog Flea and Tick Prevention Collar for Small Medium Large Dog Puppy, Black

If I could give 10 stars I would. Within 1 day of putting on my animals, there was no more itching. These are waterproof too! There is no irritation to my animals necks. I use them for 3 months and then switch to a new one.I would recommend these to all pet owners.

As of now, our Darcy Dog has had the collar on for 3 days with no adverse problems, no fleas/ticks found, and the price is fantastic...only downside is that it doesn't say exactly what ingredients are within the collar...there was supposed to be a paper inside the box describing the ingredients, but there wasn't any in mine...However, at this time, I would recommend trying it for yourself.

These collars do not work and you're left to drive then all over town to return them.I had my dog professionally groomed and deflead and put the collar on I'd spend 3 weeks of my dog has had fleas three times in that time the collae does not work.Spend your money on Sorresto - works for 10 months with no residue and NO fleas from day one.Live and relearn - you get what you pay for!

These collars work and I’m satisfied. The “natural” flea and tick collars smell so full of citronella - made me nauseous and my dog went crazy, they went in the trash.

I bought these for my dogs, & they work good. The only thing is the buckle is awful, it comes loose, so I have to keep checking them. I had no issue with rashes or sores from them. No fleas all summer, & only 2 ticks. And I live near the Pine Barrens. I will be buying them again.

These are strong enough to endure my beagle's rough housing and play. Others have broken quickly so that's important to me. But best of all of course is that they work! No fleas for my girl and it's much easier than drops or shots. Definitely a great value for the money, I'll be buying more.

I bought and applied these collars on my dogs before flea and tick season began. Therefore they should have been working by the time ticks came out. My 6 month reapplication does come up until July or August. They seem to work for fleas but DOESN'T work for ticks at all.

Great price and nice material...it soft not stiff like other brands.
