Rolf Club 3D Flea & Worm Collar for Dogs - Flea Control and Tick Treatment - Better Than Oral Flea Control - Dog Dewormer - Dog Worm Treatment for Tapeworms

This collar contains ivermectin so it is effective in repelling flea’s, tick’s, and worms in cats and dogs. I’ve used this product on my dogs and the cat collar for my cat. My pets did not experience any negative side effects from the collar. I’ve used this product for 3 years now and am very happy.

I have two pups (small to medium size) that are my companions on frequent trail runs through the forrest, often pretty bushy forests. They also are service pups who travel with me, so my guess is that if any dog has an opportunity to get exposed to fleas and other bugs, my dogs do.This collar seems to work - my pups don't have any fleas or bugs - at least I can't see any, and they aren't scratching. Their fur is soft.I like that the collar is easy to put on - it is the model of Seresto but a brown color instead of grey. By "model" I mean the way it attaches around the neck is the same. I have bought some other flea collars that have a different attachment style, and some don't stay on well and others are just a pain, or hard to fit. The clear-colored ones seem to have this problem. This one is easy to put on, it stays on, and easy to cut if it is too long for your pup.It seems water proof - they have been in the rain and the bath with no issue that I can tell.It is much cheaper than the popular name brand, Seresto (I used seresto and it seems to work too, but I go with 1/2 the price if I can!)I spent a lot of time reading reviews both of flea collars and of the monthly liquid you put on their back (e.g frontline.) I found that while a few brands of both (collars and liquid) get unusually awful reviews - maybe 20% of the available brands get these awful reviews, something like 80% seem to have very, very, similar review sets. These review sets have a majority of people satisfied, but a significant minority dissatisfied. Basically, it seems your odds of success are the same with most of the collars and most of the liquids. I like the collar better because you put it on and leave it for 4-8 months instead of having to deal with another monthly task. I think the reason why there are bad reviews for almost all of the treatments, is that none of these are 100%. They kind of sell it like that, but my vet said it is more like mosquito spray. If you have ever used mosquito spray when camping, you know it helps a lot, but you also know that it won't stop every mosquito. Personally, I also give my pups a 2x a month bath using dawn dish soap for safe measure (dawn dish soap kills fleas - probably all dish soap, actually.)

So far so good. Collar fits snugly, doesn't seem to bother my dog, no odor. Will update after 48 hours on how effective it is.EDIT: USE WITH EXTREME CAUTION!!!! I have a 29lb, 10yr old male Beagle, who is current on all vaccinations and, according to his last wellness exam (less than 2 weeks ago), is healthier than most dogs in their prime. He has no pre-existing conditions and is not on any medications. I researched this product and its ingredients throughly, for almost a week, before deciding to purchase this collar. I have given him drops in the past with the same ingredients without issue, but lately they werent having the same effect as they had in the past and decided to try a different delivery approach. Thankfully, I am a bit overprotective of my pooch and watch him like a hawk. After having the collar on for 3hrs and 19mins, he began to exhibit very odd behavior. Upon standing up from a lay down position, he was unable to walk normally. His whole body was "tilted" and he wasn't able to walk straight to me. Like he was dizzy and couldn't seem to get his legs and paws to work at the same time. When I picked him up, he was HOT to the touch. His temperature was 104.4°!! I immediately removed the collar, put him in the tub and ran cool water over him for 15mins. He was quite lethargic and slow to reapond to me. I put a call in to my vet, who made a house call, to observe him in person. She administered Sub-Q fluids and we wrapped him in a damp, cool towel to reduce the fever. After about an hour he started to perk up a bit and his temperature registered normal. Her dignosis was Accute Toxic Poisoning. If I had not been watching him or had gone to work for the day after putting it on him, he more than likely would have died or been close to it. I have never been more scared in my life and wouldn't wish this on any pet owner.

I own 4 dogs in Florida and purchased these collars and so far they're working as advertised. Will buy again.

When I first bought these collars I ranted and raved about them on Facebook and even attached to link and photos so my friends could buy them. at first they were miracle workers and killed every flea on both of my chihuahuas and it was the only thing that worked for these Floridian fleas. But after about a week and a half after I put them on my dogs they slowly began to stop working and I once again saw fleas start to overtake my dogs and now I'm trying to find something just like these maybe with the main ingredients that will last longer because spending $25 every week and a half to two weeks for two dogs is too expensive..

Even after reviewing the product info and reading all the reviews I was still stunned and I am still stunned at how well this collar worked - I did not see a single flea nor did I find any ticks and I just replaced it now with a new one just to be sure but it was still working it did not seem to have any negative effect on my dog at all. This is a great color!

This is one of the better flea collars for my dog (and cat but bought the cat version. Lol). This was the second time I’ve purchased these collars and will purchase them. Again.

I also treat with monthly flea meds. I don't know if my dogs are super sensitive, but no matter what I do, they scratch. Can't really tell a true review of this collar, but I use them and would buy again. One collar was lost on one of my dogs, but the other still has his. Not sure what the situation was to cause him to lose it, but they seem to stay on pretty good, under usual circumstances.
