The Benefits Of Dog Bones
Dog bones have a wide range of benefits for your dog and if you have a pooch, you should certainly consider buying them a bone. Here are some of the main benefits.
Bones can be extremely beneficial in the dental health of your dog. No matter what bone you choose, the chewing motion of the bone helps to clean your dog’s teeth and gums and this leads to a healthier overall mouth. By chewing at the bone, any large pieces of food that are stuck in your dog’s teeth can be worn away. You can also purchase bones that have extra bristles, ensuring your dog’s teeth are really scrubbed. This helps to decrease the chances of tooth decay and gum diseases.
Bones for dogs can be a great way to keep them stimulated. When you give your dog a natural bone with meat still attached, they have to work out how to get the different tendons and ligaments off the bone, almost like a puzzle, and this helps to keep them active and engaged. Even if you decide to opt for a synthetic bone, your dog will be interacting with the feel and taste of the bone and this will help with their cognitive development. It also gives them something to do while you are away from home or you are busy and do not have time to play with them.
Your dog has a natural desire to chew. This means that if you don’t give them a bone to chew on, then they will find something else to chew on — something around your house such as your furniture! Giving them something to chew will keep your house intact and will ensure they don’t get bored and start looking for something else to chew.
Natural or raw bones can be an essential part of your dog’s diet. These bones have a lot of nutrients and minerals for your dog, including phosphorus and calcium, as well as protein. The bones that contain marrow have aded extra nutrients too. Your dog will also love the taste of these natural bones and it mimics what they would eat in the wild.
Different Types Of Bones For Dogs
There are many different types of dog bones and they all have different benefits. You will need to decide which one is going to be the best for your dog.
Raw Dog Bones
Raw dog bones reflect your dog’s ancestral diet and usually still have tendons and ligaments attached to them that your dog has to work to get off. Not only do these dog bones contain a lot of nutrient-goodness for your pup, but they also keep your dog mentally stimulated as they try to work the meat off the bone. It is recommended that you give your dog raw natural bones rather than cooked natural bones — raw bones are softer and less likely to splinter in your dog’s mouth, which can be dangerous if you are not careful. Raw bones are also more nutrient-rich than cooked bones.
Natural Bones For Dogs
Natural dog bones are perfect for pet parents who worry about the germs in raw dog bones and whether they are likely to contaminate their dog. Quality natural dog bones have been slowly cooked, almost roasted, helping to steralize them. However, as we mentioned above, this can decrease the nutrient content of the bones and also make them more prone to splintering, which can be dangerous.
Rawhide Dog Bones
Rawhide dog bones are actually not bones, but are made from other parts of the animal. They are usually made from the inner layer of the skin or hide of cattle and horses and so can still be considered a meat product. However, they can lack flavor and nutrients too, so you will want to check that the rawhide bone you purchase has been enhanced with a natural flavor and still contains a good amount of nutrients.
Dental Dog Bones
Dental dog bones are the bones you should buy if you want to keep your dog’s teeth and gums extra healthy. They help to freshen your dog’s breath as well as scrubbing at your dog’s teeth to remove food particles and generally keep your dog’s mouth cleaner. They can also be great at preventing gum disease and tooth decay.
Synthetic Dog Bones
Synthetic dog bones do not contain any meat. The most common type of artificial bone is one made of nylon. This is extremely durable and great for big chewers. These bones can mimic the exact feel and taste of real bones, but can be safer while still giving your dog something to chew on. They also don’t usually leave a residue when your dog chews on them, so can be much easier to clean up.
Healthy chews are something you should consider if your dog is not eating their regular food properly and you are worried they are not getting a sufficient diet. These healthy chews are enriched with nutrients and give your dog a fun way to get all the essential goodness they need.
Chew toys are designed for those dogs who love to chew. These toys are normally very durable and will last a lot of chewing by the biggest of dogs with a powerful chew! These chew toys last longer than your regular bone and are much less likely to break, ensuring they are the safer option.
Natural Vs. Synthetic Bones For Dogs
Whether you go for a natural or a synthetic bone is really up to you as a pet owner. We have listed the types of bones above and their benefits and it is your decision whether you choose natural or synthetic.
A natural bone chew is going to replicate the diet your dog’s ancestors ate a lot more closely and gives them great nutrients from the ligaments and tendons that may still be attached to the bone. This also give them something to “do”, working at the bone to get all the remaining meat off and keeping them stimulated.
A synthetic bone is the safer option if you are worried about germs or the bone splintering. Your dog can chew away without getting hurt and there is a lot less debris left when they are finished. However, these synthetic bone chews don’t have the same nutritional value as natural bones and have been known to contain artificial flavorings. You will need to check the packaging of the chew you buy to ensure it is healthy for your dog.
No matter what bone you go for, it is important that your dog is chewing something because this can have great effects on their overall health.
Things To Consider When Buying Bones For Dogs
There are a few things to consider when buying a dog bone to ensure your dog gets the most out of their bone.
First of all, you want your bone to be durable. As we mentioned above, dogs are natural chewers and a bone is going to be useless if it breaks very easily. This is especially important if your dog is a big chewer or has a large jaw on them. Synthetic bones are much less likely to break than natural bones. However, if you want to go for a natural bone, raw dog bones are better than cooked dog bones, because they are less brittle and less likely to splinter, which can cause harm to your dog if they swallow the splintered pieces. You should also look for bones from strong animals, such as cows.
The bone size that you choose directly relates to your dog’s size. If you have a small dog or a puppy, they will need a smaller bone because they have smaller mouths. Similarly, if you have a larger dog, they will need a larger bone. If you buy a small bone for a large dog they could actually risk swallowing it, so it is always better to go for a larger bone if you are in doubt.
As we said above, natural bones are far more nutritious than synthetic bones because they come from animals. Bones with marrow in are extra nutritious, because this is the part of the bone where the nutritional ingredients are held.
You want to be sure that you buy a bone made of natural ingredients, especially if you are buying a synthetic bone. This will ensure your dog is not exposed to any artificial ingredients which can be unhealthy for them.
Synthetic bones are often flavored to interest your dog in them. They can be flavored with your dog’s favorite, such as bacon, chicken and beef. This will ensure your dog continues to chew on the bone and they don’t decide to give up and chew on the furniture instead! You will want to make sure that these flavorings are natural and not artificial, to ensure they are healthy for your pup.
If you’re ready to find the perfect bone to keep your dog occupied, take a look at the list of the most popular dog bones below. They are all available on Amazon.

Dog Bone FAQ’s
Are dog bones safe?
Yes, dog bones are safe, but you should always take into consideration your dog’s size and needs when purchasing one. You don’t want the bone to be too small that they choke on it and it should never be too soft that they could bite and break it easily. If your dog is an aggressive chewer, you will want to look for a very tough bone. Remember, raw bones are a lot less prone to splintering than cooked bones, so these can be a lot safer. It has been recommended that you supervise your dog when they play with their bone so you can remove any parts that break off. You should also not give your dog any left over bones such as chicken or lamb bones because these can splinter very easily.
How often should I give my dog a bone?
This depends on how quickly your dog can get through a bone. Some dogs can take weeks to get through a bone, whereas others can only take a day. Dogs can eat raw bones, so you won’t want to give them to them very often because of the calories. Experts suggest one to two raw bones a week, with another synthetic bone to keep them going at other times.
How do I clean a dog bone?
For a synthetic bone, you can simply run them under warm water and use a little brush to get the dirt and bacteria off. It is a little more difficult for a natural or raw bone and, if they start to look dirty, you should probably replace them. You should also replace these when there are a lot of holes in the bone, because this is somewhere where bacteria can breed quite heavily.
If you want to keep your pup occupied and mentally stimulated, a dog bone might just be the thing. Whether you’re looking for a synthetic bone that they can chew on or a raw bone to add to their diet, these bones are a great way to ensure your dog isn’t bored and doesn’t chew the furniture, while also helping to keep your dog’s teeth and gums clean. With so many different types of bones and flavors out there, you will be sure to find one that your dog will love. Just remember to take into consideration your dog’s breed when purchasing a bone, making sure the bone is the right size so they cannot swallow it or any splintered parts.
