GREAT BUY!
I bought this for my 4 legged granddaughter who lives with me. She had started scratching and rolling around with fleas. We put this on her and it started working a couple of hours. For the first 24 hours, she acted like it was making her sick but it quickly passed. It has been a couple of weeks now and “no more fleas or scratching”! It was more expensive than some other flea collars but it works out because it lasts longer. Plus, she’s worth the money!! So glad I bought this for her!!

PetArmor Flea Collar
My girlfriend’s dog has been itching a lot lately and, although we haven’t found fleas yet, decided to get this to help her constant itching. It must have been fleas because she’s been itching quite a bit less lately. It’s worth the higher price point than I’d usually want to spend. It was a tad difficult to get to fit onto her neck, partially because I didn’t want to touch the collar too much with my bare skin and also because she’s wild and didn’t know what we were doing. So far, I’m pleased with this collar and would buy it again, though the price is still a tad prohibitive for me.

This Collar Is Amazing! It Worked Wonders!
I could cry happy tears of joy right now. We fostered a cat for a week and she infected my poor dog with fleas! I did the expensive three month regimen and still found a few fleas after doing everything by the book. They didn’t look very lively but they were still there and I was feeling very defeated. Instead of doing three more months I put this flea and tick collar on my large 85 pound Labmaraner. The collar fit her very thick neck and I still had extra length to cut off so this should fit most any size dog. The collar came in a nice metal tin with detailed instructions. There was no chemical smell that I could detect. I did wear disposable gloves when I put it on her just to be safe. She’s been wearing this collar for around a month and it finally killed all of the fleas. There’s been zero skin irritation which is very important to me. My dog tolerates the collar like it’s not even there. I was desperate to find something that was both safe and effective and I finally found exactly what I needed with this extended release flea and tick collar. When this collar wears out I’m putting another one right on her. We take her for lots of walks on trails and in wooded areas and I frequently have to remove ticks from her. I was afraid of these collars because I bought one in the past that literally burned the hair and skin around my dog’s neck within a few days. This collar didn’t affect my dog in any negative way. She doesn’t itch anymore and is so much happier. I will be buying this collar again and would recommend it to others. The quality is excellent and the price is very fair to eliminate fleas. Five huge stars!

Good.
PetArmor Extend Flea & Tick Treatment & Prevention Collar for Large Dogs Above 18 lbs., 8 Months of Protection, Odorless & Non-Greasy, Waterproof, Kills Fleas, Ticks, and Flea Larvae, 1 CountThis is a good quality and value flea collar. We have a larger sized dog that is around 70 pounds. We live near a creek and deal with a bit of fleas through the warmer months. We have already seen a few in the new year now that its warming up. This collar has seemed to help, and haven’t seen any on our dog since we put it on. It is long lasting and looks alright. Good quality and its effective.
I am pleased that after not receiving this book, the seller has been very prompt in resending it. I have it now and can’t wait to start reading! –
The quality is very poor
They were melted. They are supposed to be crispy, but the chocolate was melted and made the wafers soggy/stale.

sweet fit all flea collar
good size collar that came in a nice metal tin. that could be useful for other stuff.the material is rubbery like so its super nice to handle and even easier to put on, got a 20 lb Schnauzer mix and it was quite easy to put it on, my guy had no complaints, seems comfortable and has been wearing it for while now.just slide it on, and cut the leftover, so large that can fit a big dog no problem or adjust to smaller dogs, you just have to cut to fit. since the material is rubbery strong like, its bound to last for a long while, got no doubts on that.no side effects on my small doggie which is expected as its a known brand and has been effective so far at keeping fleas at bay, and it does work hard all day since my dog is mostly outside.pretty good value since i wont have to worry about it for a whole 8 months and that is something sweet to think about.
