Great Work

I didn't realize that I wasn't getting the medicine for the eggs and larva. This stuff works great and is cheaper, fantastic product for my Golden Doodle

Big Savings and Quality Product!!

I have been using K-9 Advantix for quite some time. Switching from K-9 Advantix to Frontline Plus, and back to Advantix. I kept switching because i couldn't figure out why such a mess on my dog's fur. It would clump up so bad after I took great care on making sure it went right on the skin. It just would not dry and absorb through the skin. I was constantly cutting it out and cleanup was out of control. So, i took a chance on trying Advecta. Advecta absorbs quickly and doesn't leave a clumpy, gummy mess and works great. The savings is great and the product is overall better.

Same ingredients as the other brand, half the cost

Has the exact same ingredients as the k9 advantix for less than half the cost. I put it on him yesterday and always notice a difference. I was shocked at the gore much cheaper bit is than the other brand, and the only difference I found is the cost. I guess if you have money to waste buy the other brand, if not highly recommend this!!
