Tick protection is REQUIRED of dogs in country

This stuff seems to work, keeping ticks off my dog, better than the white collar repellant. And it seems to not get the dog coat "oily" as harts mountain product did/does. Comes in about one oz doses that is put on the dog back and neck where the dog is least likely to lick him/herself until it dries on skin. Time will tell if it works over the monthly duration it is supposed to last. Ticks have become a major problem in central Michigan and everyone in rural areas simply must protect the dog from ticks. Lyme's disease is everywhere these deer ticks live.

Great product!

My fur baby was infested with fleas and lice. I bought a natural treatment at Pet smart that was a total waste of my money and the reason we got where we were at. After shampooing my dog and dried him, I applied the product and I couldn't be happier. He is free of bugs!

Same as popular brand but a lot cheaper

Same active ingredients as Frontline Plus but in much more better price! I received this product recently to try and share my opinion, i have to say that got online and started and checking it out to see if it is the same as Frontline Plus, which I have been buying before, (at a much different price, higher price!) After my research I decided to give it a try because the active ingredients compare exactly, they also come in same percentages to the product from Frontline brand. The weather has changed and i am not waiting to see any visitors on my dog, it has been more than a week since i applied and she still clean, i will keep checking and update this review. also the skin that came in contact with the product it is in a healthy condition. i think it is worth the try and if it keeps working as now i definitely buy again.
