Review: BEST Flea and Tick Prevention at Our House! - Have always used Vectra 3D and it has never failed! No ticks! No fleas! Our boy, a hundred pound chocolate lab, sees the med and immediately sits for application--HE KNOWS! No better rating than that! We have NEVER had any adverse side effects or reactions with this product. We also know that the protection lasts! It is so worth the price! If you've ever had to rid your home and pets of fleas or ticks, or dealt with needing to frequently worm, you know it is costly and time consuming! With Vectra 3D, we don't have that extra hassle and expense! Yay!
Review: The best otc flea treatment I've ever used! - This is by far the best flea control topical treatment for dogs that you don't need a prescription for. I've never had luck with otc flea treatment up until I found this. It was relentless for my giant pit. The cats had a few as well but not the endless infestation like our pitty. The first couple of hours she went kinda nuts because they were running and freaking out but then she got calm and slept soo incredibly good. The next morning they were about 90% gone. I have vacuumed daily as well and emptied the canister after every use. The first couple of days I had a lot of fleas jumping on me. Last night was the 4th night and I spent about 30 mins combing her from front to back only to find about 10 total that were actually moving very slow and almost dead. I combed my cats last night and only found about 5 on all of my cats... I have over 10 cats btw 😁. I don't want to publicly say the exact amount lol. This morning she has zero on her. I have also washed all of her bedding as well as the couch blankets I use to protect my furniture. She goes outside several times a day and that is actually my next area to treat. I'm in complete shock. I got front line to put on my cats but I haven't had to use them fortunately. Most treatments in the past is a very small vile and you only put it in between the shoulder blades. However this product is a larger vile and you start at the neck and apply a line down the back from neck to tail. I'm in utter shock and soooooo relieved. My girl will finally get her skin back to normal and hopefully her patches of missing fur will come back. I can't take her to the vet because I can't physically get her into our truck. She's not leash trained and she doesn't know how to get into a vehicle and unfortunately she's over weight. Not morbidly but she's definitely over weight and she would need a muzzle because I don't know how she would react around strangers poking at her. I give all shots myself.
