x3 on the 10 percent permetherin and bayer tree and shrub or ortho tree and shrub max...just make sure it is fertilizer free and 1.47 percent active ingredients...just pour 15 cc's on your dog and rub it in to the skin on his topline and/or belly...you have to break the cycle in the yard and use any poison that disrupts the flea cycle...once the fleas are gone keep other dogs and cats out of your yard...
I treat my dogs about twice a year and fleas are always under control...the dogs are kennelled on concrete but I let them run in the back yard about 1 hour a day...the yard is sandy but no fleas...
