It’s a habit left by dogs before that whether there is meat on the bone or not, it seems to have great attraction for dogs. Basically, when a dog sees a big bone, he will eat it happily. Of course, one of the reasons why dogs like to gnaw bones is to help them grind their teeth, but it can’t fully explain the problem. This shows that there are other factors that lead to this phenomenon. We know that many carnivores like to eat bones, whether there is meat or not. That’s because the last fat reservoir on a skinny animal was its bone during the hard times of food shortage. More than half of the components of bone marrow are fat. In addition, there is a kind of fat called bone fat in bone. It connects all kinds of calcium to form bone. Although the digestibility and concentration of this fat are not so good, it is also a large source of fat. From this, if you are a predator and your prey is in poor physical condition at some time of the year, it is particularly important to try to eat fat. It’s a matter of life and death whether you have strong enough ability and willpower to crush and clean the big bones, and whether you can digest those bones after eating them. So it makes sense to like eating bones.
We should also pay more attention to the selection of bones. We should try to choose big bones that are not easy to be chewed by dogs. Therefore, many carnivorous species, including hyenas and some extinct dogs, such as wolves, have specialized teeth that can crush bones. The masseter muscle has also evolved to be extremely powerful and easy to chew bones. In this respect, although our domesticated dogs don’t have the special sharp teeth, their jaws are stronger, and even an ordinary dog can have a bite force of almost 490 n / cm2, so they also have the ability to slowly eat the largest bones. Of course, the most important thing is natural selection, which makes all surviving dogs have a natural desire to gnaw bones. It’s a trick of natural selection to make the behaviors necessary for the survival of individuals and species particularly pleasant.
So it’s a good choice to take a big bone for the dog to chew. But the best feeding is raw bone, and it is the kind of big bone that is not easy to be swallowed by dogs. The cooking process will let the bone fat seep out of the bone, and often melt the fat in the bone marrow, so the dog’s desire to eat the bone will be reduced. In addition, the cooked bone will certainly be easier to bite than before, which can make dogs easily bite into small pieces, thus increasing a certain risk. If a dog eats such a bone, it is easy to make the broken bone slide the dog’s gut, or even the risk of the bone stuck in the throat. In fact, nowadays, the big bone only plays a role of grinding teeth, and the number of feeders who take bone as food is also slowly decreasing. For the sake of dog’s safety, we only chew the big bone which is not easy to swallow, instead of the thin and soft chicken bone. Therefore, the selection of bone should also be considered to avoid the threat to the dog’s health.
