Instructions
Directions for Use: It is a violation of Federal law to use this product in a manner inconsistent with its labeling. Remove collar from package, unroll and stretch to activate insecticide generator. As the collar begins to work, a fine white powder will appear on the surface. Do not use on puppies under 6 weeks old. Do not unroll collar until ready to use. Place the collar around the dog's neck, adjust for proper fit, and buckle in place. The collar must be worn loosely to allow for growth of the dog and to permit the collar to move about the neck. A properly fitted collar is one that, when fastened, will snugly slide over the pet's head. Leave 2 or 3 inches on the collar for extra adjustment and cut off and dispose of the extra length. Consult a veterinarian before using this product on debilitated, aged, or medicated animals. If used on pregnant or nursing dogs, do not replace collar until the puppies are at least 6 weeks old. Sensitivity may occur after using any pesticide product for pets. Some animals may become irritated by any collar if it is applied too tightly. If this occurs, loosen the collar.

The collar will begin to kill fleas, ticks and flea eggs and larvae immediately. Its full protection against harder to kill ticks will be built up within a few days after being placed on the pet. For continuous flea and tick protection under normal conditions replace the collar every seven months. Under conditions where pets are exposed to severe flea and tick infestations, it may be necessary to replace the collar more frequently. Wetting will not impair the collar's effectiveness or the pet's protection. If the pet goes swimming or is out in the rain it is not necessary to remove the collar.

Dogs didn't fight the idea.
Good fit and and dogs don't notice them . Latch may not hold to active dogs in rough terrain, but should be good for average dogs.

An Excellent item.
My Service Dog is very happy she has this. The people that live here, it's a home for the disabled, have cats, those cats have fleas. My Dog has suffered, no more. With this collar and frontline, we have a good defense against the blood suckers.
