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.

My Dog's Favorite Nylabone
Flavor Name: Bacon & Beef, Size: X-Small
I've been testing out Nylabones the last couple months for my chihuahua puppy. He's a heavy chewer and too easily tears apart many of them, then others are too hard and I take them away because I fear for his teeth. This set is his favorite so far. He doesn't care about the peanut butter ones, loves the beef one, and is absolutely obsessed with the bacon one. He walks around with it in his mouth whenever he goes anywhere. Unfortunately, my senior chihuahua also loves the bacon one and there is now an ongoing feud over it, so guess I'm buying another pack. I like that these are just a little chewy without being too soft, but I still recommend keeping an eye on them as even my puppy has managed to start to get little pieces off. But it's more as frayed strings than chunk like I've had happen with some of the softer ones.

Good for satisfying destruction urges
Flavor Name: Bacon & Beef, Size: X-Small
I have a 30 pound dog who doesn’t want a super hard chew toy, but something that he can destroy into pieces. It really helps with his destruction urges. Even though my dog is 18 months old, this puppy chewer is perfect for him. Once he chews it up into little pieces, I am able to pick them up, and by the time he is done, he is relaxed and or asleep. Highly recommend for puppies, of course, but if you have a dog who needs to destroy, this is the perfect thing to do that with! It is good value for the money and better than other household items that he could be chewing on.
