Directions for Use

It is a violation of Federal law to use this product in a manner inconsistent with its labeling.

DO NOT USE ON HORSES INTENDED FOR SLAUGHTER

Feed the recommended dosage of Farnam® SimpliFly® Feed-Thru Fly Control to each horse separately to make certain he receives his full portion. This product should be fed top dressed on grain or mixed with the horse's total ration to provide 6.8 mg of diflubenzuron per 100 lbs. of body weight. For an occasional finicky eater who does not accept new feeds readily, mix this product with sweet feed or grain ration.

Start feeding Farnam® SimpliFly® Feed-Thru Fly Control early in the spring before flies begin to appear and continue feeding throughout the summer and into the fall until cold weather restricts fly activity. This product contains an insect growth regulator which prevents the development of house flies and stable flies in the manure of treated horses, but is not effective against existing adult flies.

In some cases, supplemental fly control measures may be needed in and around paddocks and buildings to control adult house and stable flies which can breed in other decaying vegetable matter or silage on premises, or that migrate in from other areas.

Farnam® SimpliFly® Feed-Thru Fly Control should be used as part of an integrated pest management program aimed at reducing fly populations in the horse's environment. Consult your retailer for program recommendations. In order to achieve optimum fly control, this product should be used in conjunction with other premise and on-animal products as well as good management and sanitation practices.

Helps with separation anxiety, keeps dogs busy
Size: Medium (Pack of 1), Product Packaging: Standard Packaging
Have been using kongs for my labs for years. Brand new the kongs do have a strong rubber smell. Try putting the Kong in a pot with water over low fire to help reduce the smell. Stuff with favorite treats or fill with peanut butter and freeze. Will keep dogs busy and chewers with an indestructible toy

Very durable and my Dutchie loves it
Size: X-Large (Pack of 1), Product Packaging: Standard Packaging
This is one of many Kongs I have purchased through the years. This one was the extra large that was purchased for my Dutch Shepherd. Every night at bedtime, he gets his Kong stuffed with some dry food, treats, and a nubs bone to hold everything in place. He loves his Kong and runs for his crate at bedtime. Usually, he doesn’t eat the treats immediately. But sometime during the middle of the night, he will wake up and eat. Every Kong I have purchased through the years has been very durable. I highly recommend this product for all sizes of dogs.

Best chew toy and training item on the market!
Size: Small (Pack of 1), Product Packaging: Standard Packaging
I'm a Dog Trainer, specializing in early canine education with Puppies between eight and 18 weeks . The Kong is the best thing you can give a dog! You can stuff these things with all kinds of yummy things. I love to get creative with the Kongs. Adding novelty to your dog's life improves their brain health. I can't even give examples because I would be here all day. For dogs who eat kibble you can soak your kibble in water or better yet bone broth, then once it's soft, fill the kong with the kibble and put it in your freezer. Keeps your dog busy for a long time, you don't have to buy extra stuff because you just give them the kibble you're already going to give them. (I recommend getting at least one, but up to six for each dog so you can give them their entire daily allowance of food in the Kongs). The licking /chewing helps them relieve stress and gives them something to enjoy inside their crate. I learned this from Dr. Ian Dunbar and I highly recommend his training courses on a platform called Dunbar Academy to learn how to properly raise a Puppy into the best dog you've ever had. He has helpful information for older dogs too, but you really want to train your puppy properly so you can avoid the behavior problems in the first place. It's super cheap too, and easy to learn from. Plus these are great chew toys for heavy chewers because as long as you get the right size for your dog, they can't destroy this thing! AND it bounces, so you can actually play fetch with it like it's a ball. Every single dog deserves a Kong, so if you don't already have one, go ahead and do that right now. You won't regret it, and your dog definitely will love you more.

My pup loves her Kong
Size: Small (Pack of 1), Product Packaging: Standard Packaging, Size: Small (Pack of 1), Product Packaging: Standard Packaging
My little pup loves her Kong! She’s about 14 pounds so I recommend any dog with that size to get the small size. The quality is great. Extremely durable, but still workable enough for her to get in and find all the goodness!

FOR SHORT TIME USE
Size: X-Small, Color: Ring Bone
My puppies love this. After a couple of weeks, it is worn so I throw it out and buy another since it's reasonably priced. I don't want them to actually ingest a chunk of this.
