    IF YOUR READING MY COMMENT BUY THIS NOW!!

    I tried everything flea shampoo dog flea spray to get rid of fleas and a different flea collar I got from petco nothing worked. I would give my dog a bath with the flea shampoo they all would all be gone but then next couple days alot of fleas just come again. He had so much fleas it made me so sad hearing him cry he would scratch and bite his but and tail so much his hair came off I was heartbroken 💔 I didn't know what to do so I saw this collar alot of good comments so I bought it. For only $60 dollars my dog isn't crying anymore he doesn't have so many fleas I couldn't count them. His hair is growing back and when I check if fleas on him when I see one it's dead collar kills them so I just pick it off him and throw it in the trash. THANK YOU SO MUCH!!!!! My baby boy king is so much happier now

    BUY IT!

    I NEVERRRRRR write reviews but I had to for this product! It has worked a literally miracle for my boxer! He’s an outside dog and one day I noticed he had hundreds of fleas on him. He also had some scars from scratching so much. I tried several flea baths that just didn’t work. When I started researching flea collars I became VERY skeptical because there a lot of reviews about them irritating the dogs skin. But there were many more good reviews also. So I bought the 8 month Seresto collar and put it on my dog. I watch him very closely for the first 2 weeks and realized that the collar won’t harm my boxer. Great! Now let’s talk about results... Within 2 days, like the products claims, the hundreds of fleas were literally down to about 20-30ish. I gave him 2 flea baths within those first 4 days and he was FLEA FREE! No more scratching every couple of seconds. It’s now about 45 days later and ALL of his scratch scars have healed. He’s way more at ease and comfortable because he’s not being irritating by those damn fleas anymore. I definitely recommend this to everyone. But there’s definitely some dogs that the collar could possibly cause damage to(based of reviews I’ve seen). So just watch your dog very closely for the first week or so. BUY IT! :-)

    The best

    after trying every kind of flea medication , shampoo, spray , etc for my two dogs, i had almost given up hope, until i decided to try the flea collar. all i wanted was for my dogs to feel better and not have to scratch all the time. after putting the collars on, within 24 hours there was a noticeable difference but not completely gone, after 2 - 3 days i was shocked and filled with glee that all fleas were gone or dead. after one month, my dogs are still flea free , as is my home. the price may seem a lot but i cannot express enough that this collar is worth every cent. there is no other product that protects my home from fleas like this does
