Description

Microcrystalline Hydroxyapatite (M.C.H.A.), also known as Micro-crystalline Calcium Hydroxyapatite Complex (M.C.H.C.), is derived from raw bone and prepared by a special low temperature process (below 37° C) to preserve the protein content. The calcium thus provided is in an extremely bioavailable form. Vitamin D3 is because it is required for the absorption and utilization of calcium and phosphorus and is especially important for normal growth and development of bones and teeth. Vitamin K (both K1 and K2) is added support the synthesis of osteocalcin, the protein in bone tissue upon which calcium crystallizes.* However, because of its role in blood clotting, patients who have a problem in this area or who are taking medications to prevent blood clotting must carefully monitor their intake of vitamin K.

For an MCHC product without vitamin K, see #834.

Balls
Size: Medium
My dog loves chasing these balls. He seems to love the squeak! They fit the chuck it stick perfectly, and are great replacements for the originals that came with the stick.

Nice set of balls
Size: Medium
The squeaker quickly became my dog’s favorite ball and has replaced the fuzzy tennis balls. My dog is a nonstop fetcher and these chuck it balls are durable and fun.

Soild

The orange and blue ball is perfect. Once start taken because the because the blue noisy one was a little to easy for my dog to start ripping pieces off. Will say most toys do not survive his chewing.

Aggressive chewer who loves fetch approved!!
Size: Medium, Size: Medium
I highly recommend the Chuck-It brand in general, especially for dogs with an aggressive bite. These balls are awesome and are the most durable balls I’ve bought for my 50 lbs lab mix. He has not been able to break one of them yet and we’ve had a few of the squeaky balls for months. They are a bit pricey but worth it. The one in the pic has been used for months, lives outside and you can see it’s still in great shape.
