Sulfate of Potash 0-0-50 Granular Fertilizer
Southern AG Sulfate of Potash 0-0-50 Granular Fertilizer is a concentrated potassium fertilizer designed to help correct potassium deficiencies in low-potassium soils. With a 0-0-50 fertilizer analysis, it delivers soluble potash without adding nitrogen or phosphate, making it a targeted solution when plants need potassium support for stronger roots, sturdier stems, healthier tubers, and improved overall plant vigor. The product contains granular potassium sulfate and is intended for soil application, not spray use.
This granular potash fertilizer is suitable for vegetables, flowers, shrubs, and lawns. It may also be used to help address potassium deficiency in plants such as avocado, beans, corn, cherries, citrus, grapes, palms, and roses. Potassium plays an important role in root growth, water regulation, photosynthesis, plant strength, winter hardiness, and disease resistance.

Great for my pitbull, worth the price! the warranty isn’t what it seems so check their site first.
Color: Orange Squeak Toy, Size: Medium
I’ve now purchased 3 and I don’t see myself ever stopping! My 55lb Staffie (pitbull) has absolutely obliterated every ball and toy (rope, rubber, stuffed) before this one in a matter of minutes. You take your eyes off it, and the next time you’d look back it would be in pieces. Kong Xtremes and other “indestructible” toys only lasted a week, tops. He also goes nuts for anything that squeaks, so keeping him happily entertained for a while was a challenge because the second he’d chomp down on a squeaker, it’d break. He’s now had this blue squeak ball for a MONTH and it STILL SQUEAKS!! He regularly falls asleep with it still in his mouth, or tucked under his chin. That’s how obsessed he is with this thing. I would 100% recommend this to anyone who needs a seriously durable toy for their super powerful chewer as that’s been my experience! This material is super bouncy and he can bite down (unlike some rubbers, Kong/West Paw) without puncturing it somehow. It’s perfect for fetch, and floats too. He’s never had a toy last this long, so this is a welcome break for my wallet despite being a more expensive toy. I was buying a few toys every week until we tried this one!
Cons: The first two balls didn’t squeak after a few days, so maybe they’ve improved something since then. The warranty replacement process is more tedious than others like West Paw, and only replaces them ONCE. It’s also requires more force to squeak this given the nature of the material, but since it extends the life of the squeaker I’m totally fine with it.

This ball has lasted and still have it after many months or longer. My dog loves it.
Color: Pink Squeak Toy, Size: Medium
My Belgian Malinois can really chew through inferior play toys and balls, etc., and this is one of the few that has lasted a long time, and he really likes it. Another bonus is that it gets quite slippery with his saliva and the ball will bounce a little bit unevenly, so it can either slip out of his mouth or bounce in an unexpected direction that can fool him. He has such quick reactions that is hard to get a ball past him, but with this ball, I can score extra points on him when he can't block it. Otherwise I have no chance, and he beats me every time.

Please go back to the original ball design and squeaker!!
Color: Pink Squeak Toy, Size: Medium, Color: Pink Squeak Toy, Size: Medium
Review update: I am updating my review for a few reasons. 1) The ball I ordered below was the 3rd time I purchased it. I originally bought one years ago, Pre-Covid, for my old pitty. My now Corgi, Jett loved that ball so I got a 2nd one for times when we couldn’t find the original. Well, the ball was slightly larger, the squeaker stopped working, and Jett preferred the original. 2) The newest one doesn’t squeak at all and is also slightly larger than the original. The original fell down the sewer drain that is in our backyard, and we lost the 2nd ball, so we ordered the ball again. My husband ended up having to retrieve the original from the sewer drain because Jett would pace around the sewer looking for the original. I ended up returning the 3rd ball because Jett doesn’t want anything to do with it & it doesn’t squeak. The video I provided is Jett squeaking the original that is at least 5-6 years old. I highly recommend the company go back to the original design that has not only stood the test of time and heavy use but is also the preferred size and for some reason has a much better, more reliable squeaker.
I bought 2 of these balls for my Corgi mix and another for my son’s girlfriend’s Golden Retriever. Both dogs love the ball. They love the squeak and the ball is very durable. The ball doesn’t easily squeak by hand but will when they bite down on the ball or when it bounces. Speaking of, it has a decent amount of bounce to it too. Our dog loves to jump in the air to catch it after it bounces off the ground. I highly recommend this ball for medium and large dogs.

Great fun for our dogs!
Style: Original
My dogs can’t get enough of this very noisy ball. We have one outside and one in their playroom. It is very noisy. It is very hard. So, I’d say a room with fine furniture is not the place for it. Ours bang it around pretty good.
Our boxer did split one, biting it. But, she’s a serious chewer! Our other dog carries it around sometimes but hasn’t been able to damage it yet. So, I’d say for most chewers it’s going to last a long time.
It’s a great toy but in most households I’d say basement or outside. Again, it’s hard and did ding a few baseboards.

Superb!
Style: Original
My dog absolutely loves this ball. It's too big for him to fit all the way in his mouth, so it's held up pretty well and still makes the sounds.
