Nutrients

Nitrogen 3% is the mineral element used in the greatest quantity by turf. Nitrogen is a component of many of the biochemical constituents of plants, including chlorophyll, amino acids, proteins, and enzymes. The addition of Nitrogen fertilizer can provide the ideal conditions for a dense attractive lawn.

Phosphorus 18% The proper level of phosphorus in your grass is essential for root and early plant development. Its primary role is in the storage and transfer of energy. Without sufficient P, normal growth and development cannot occur. Phosphorus fertilizer effects on turf are usually more subtle and, while not as readily visible, are still very important.

Potassium 18% is involved in carbohydrate formation, photosynthesis, enzyme activation, and the formation of proteins. Potassium fertilizer plays a role in photosynthesis, and carbohydrate production is reduced when K is deficient. A plant deficient in Potassium can be more susceptible to stress from drought and temperature.

Info 

For best results, water the lawn for 20 minutes within 24 hours of application. Water is essential for maintaining your lawn, and your lawn should receive 1-2 inches of water per week. Fertilizer will not treat a lawn that is suffering from disease, pests, weed infestations, or drought, and these conditions should be treated separately.

Durable toy, keeps them busy
Color: Red
our trainer said our dogs needed cognitive toys and lick toys to help them calm down. I had doubts about this toy. I was pleasantly surprised when it kept them entertained off and on throughout the day. One would take a break and the other would start batting it around and licking at it. I squished some soft treats into the stem section, crunch treats of various size into the top hole (a couple freeze dried chunks of chicken that I know wouldn't come out easily), and mashed some squishy sweet potato treats into the side holes of the top. While it did take a bit of time to prep with all the different types of treats, it really kept them entertained for a long time. They are 40 pounds and decent chewers and haven't bitten off any rubber bits. Very durable.

Favorite toy of all time
Color: Red
I have had my dog for 12 years and this is truly the BEST toy I’ve ever bought her (and I’ve bought probably hundreds). I squish the soft-style treats into the holes and it keeps her occupied for a good chunk of time. She loves it. I usually do it multiple times a day with a few different types of treats. She is an extremely aggressive chewer and has never damaged this toy. Now that she’s older I’m especially appreciate of this toy because it keeps her brain active and gives her something to do when she’s not feeling up to a walk.

Tough toy but even tougher to get clean!
Color: Red
My puppy is an aggressive chewer and he was only semi-interested in this toy. It hasn't been my favorite, either, due to it being pretty difficult to clean thoroughly. The toy is, however, very durable and its thick rubber has held up to the many bounces on hard floors and tough chew sessions it's been subjected to over the past few months.

A pup favorite and has held up well!
Color: Yellow
My adult dogs really like this treat feeder and love working to get the goodies out of it! It’s held up well over many months despite their biting and gnawing on it, so a good purchase overall. It’s also different than the usual Kongs so adds some variety to their feeder puzzle repertoire to keep up the diversity of mental stimulation.

Not tough enough
Color: Red
Finding durable chew toys for my pup is a challenge. When I placed a medium dog biscuit inside this, it kept him busy for awhile. But then I noticed small pieces of the toy around the house and discovered that he had managed to shred it. I've since discarded it and continue to search for toys guaranteed to be safe for "aggressive chewers".
