The Importance of B12 for Dogs

In this article we will examine the importance of B12 in your dogs daily diet, and look at what we consider to be the best  B12 for dogs available on the market today!

B12 is a vital vitamin that is required for numerous bodily processes in dogs and cats, including the brain and nervous system, cell development, protein synthesis, fat and carbohydrate metabolism, and red blood cell formation.

Your dog’s essential organs (i.e., liver, heart, brain) will not function correctly if you don’t have enough of this vitamin, which will result in sickness and perhaps death.

Cobalamin (B12) deficiency can be caused by a variety of disorders,

Various breeds are prone

Cobalamin malabsorption can also be hereditary in certain dog breeds, such as:

  • Beagles,
  • Border Collies,
  • Shar Pei’s,
  • Giant Schnauzers, and
  • Australian Shepherds.  
  • The signs of intestinal cobalamin absorption impairment will vary depending on your dog’s health, and how long he has had the condition.
  • Border Collies display symptoms around six months old, whereas Giant Schnauzers and Beagles manifest them approximately two or three months later.

As previously stated, a vitamin B12 deficiency that goes untreated can lead to more serious issues including severe gastrointestinal illnesses and weight loss.

Fortunately, however, the solution is simple: whether the issue is due to nutritional insufficiencies or an inherited condition, B12 supplements could assist with systemic deficits caused by metabolic or genetic abnormalities.

How much B12 should I give my dog?

Just as it is for people, B12 vitamin supplements can be given to dogs in a variety of ways. The most popular method is by oral supplement, which may be mixed with food or water and delivered directly to the mouth by syringe. Increasing the amount of meat consumed by your pet will also help you meet his nutritional requirements.

How long until my pet shows signs of improvement

As the pet is ingesting vitamin treatments or injections, the veterinarian will check the pet’s blood frequently until the B12 level is acceptable. While taking supplements, increases in appetite and energy, weight gain, and any gastrointestinal issues should become apparent.

In most cases, a few weeks of supplementation will begin to show benefits in the afflictions caused by deprivation; however, breed and medical condition of the animal will determine whether it needs to take them in the short or long run.

What does B12 do for dogs?

B12 is a water-soluble vitamin that actually comes in two forms – Methylcobalamin and Cyanocobalamin.

Methylcobalamin and Cyanocobalamin are the chemical compounds through which B12 functions within the body, supporting blood formation as well as neurological function. These cobalamins are essential for nervous system health and help out with the myelination of nerve cells along with cognitive development.

They also prevent damage to nerves caused by oxidative stress due to their antioxidant properties!

What’s even better is B12 can be found naturally occurring in certain foods like fish, beef, liver & chicken eggs, just to name a few! It can also be taken via supplements or injections if needed depending on your dog’s situation, so don’t be afraid to talk with your vet about b12 and how it can help them!

The most usual reasons for cobalamin insufficiency in dogs and cats are chronic and severe small intestinal illness, as well as EPI (Exocrine pancreatic insufficiency). Current research revealed that 82% of dogs with EPI had deficient cobalamin.

Does B12 increase appetite in dogs?

Your dog’s appetite will improve because they will be absorbing the nutrients in their food. Your dog’s digestive enzymes will work properly to ensure a healthy amount of Vitamin B12.

Can you give a dog human vitamin B12?

The answer is yes! As long as you get your vet’s approval. However, there are supplements made specifically for dogs and their unique nutritional needs, which may be a better option.
