What is Glucosamine?

Glucosamine is the mixture of two most important compounds which are glutamine and glucose or amino acid and sugar respectively. Naturally, the dog’s body produces enough amounts of glucosamine already but with the passage of time and health conditions, the amount of glucosamine start getting low. There could be many reasons behind it and age is the main factor among all.

Having the good amount of glucosamine is necessary for the body of dog otherwise the dog start feeling pain, especially in the joints. This is why as a dog owner you need to consider giving your dog the supplements which can help the dog body to produce enough glucosamine so that your dog can live longer without feeling any pain or having trouble to walk etc.

Definitely, the supplements are not the only solution to produce enough amount of glucosamine in dog’s body. There are many glucosamine foods too which can increase the amount of glucosamine. But increasing the amount of glucosamine through food is the very slow process. That’s why vet suggests giving the glucosamine to the dogs directly.

What are Different Types of Glucosamine?

There are many types of glucosamine but it has been usually divided into three which are NAG, sulfate, and hydrochloride. These three have different properties and has been given to the vet on the basis of their requirements. You cannot go with any of them without the vet prescription as you may give the wrong type of glucosamine supplements to your dog. Here is the difference between three of them:

N-acetylglucosamine or NAG is the natural form of glucosamine which has been founded on the shell of certain shellfish and insects. It is derivative of glucose which is the part of the synovial fluid. This fluid lubricates the joints.

Glucosamine sulfate is the most common and popular type of glucosamine because most of the supplements contain it. It is popular because the researchers have worked on this type of glucosamine most as compared to others. Like other glucosamine, it has been extracted from the shell of the shellfish. It is superior because it contains the good amount of sulfate which repairs and even build cartilage.

Glucosamine hydrochloride is same as glucosamine sulfate except it does not contain the sulfate. That’s why the doctors say that it is less effective. This type of glucosamine is also found and extracted from the shellfish shells.

Foods with Glucosamine

Like human and dog’s body, the glucosamine has been found in other animal’s body too like chicken, pig, fish, cow, vegetables and even in the fruits too. Fulfilling the requirement of glucosamine in the dog’s body to give him relief from the joints pain and treating other health conditions, you can go with the diet which is rich in glucosamine. The lists of food which are rich in the glucosamine contain the following items:

  • Beef trachea
  • Chicken feet
  • Pigtail
  • Beef knuckle bones
  • Shellfish shells
  • Lipped mussels (green)
  • Broth of bones
  • Ginger
  • Blueberries
  • Turmeric

These are the common food which can also be given to the dog or purchase the dog food which contains these ingredients and mainly made from them etc. Although, you can purchase them raw from the market and give in the way which your dog likes to eat.
