        Comments about (Blue) - 21-55 lbs:

        in a once-monthly regimen, I just gently squeeze about a third of the product out onto each of three areas: back shoulder, the mid-back, and the top of the rump for each dog. I do this right after I give them their heartworm oral doses. Then I make a fuss about how wonderful and brave they were and give them a double portion of their favorite small treats. If another dog comes into the house and is not protected, I sprinkle some Fleabuster around, according to directions. They look forward to their treatment day and I have no worries about parasites on my dogs, or in my house, for a month. How easy is that? Vectra 3D works very well, but remember NOT to apply it if your dog has a cut or scratch as it really irritates their skin. In this case, call your vet for advice.
