Works great
This products works as good as name brands with no side effects on my little one. Quick easy and effective. Price was amazingly cheap compared to band names. It gives dog parents the ease and safety of taking care of their fur babies without the nightmare prices and side effects.

Protects your friends
I just installed / applied this today on both puppies. It is not fun to apply on long haired dogs but I know it works well and will effectively protect them so well worth the effort. Will be applying again next month just not sure what weight my puppies will be at then keep in mind to weigh and order the right dosage pack.
