Dogs require a variety of vitamins to maintain health and homeostasis. Vitamins are organic substances that are required in small amounts to sustain health and growth in all mammals, including dogs. Dogs can synthesize many vitamins through natural bodily processes, but they cannot produce sufficient amounts to meet their daily needs, so they must obtain them from food or supplements. Commercial dog food diets labelled complete and balanced are formulated to contain all the vitamins, minerals, and nutrients a dog needs. However, dogs with specific medical conditions or deficiencies may require additional vitamin supplements, which should be given only under the supervision of a veterinarian.

Fat-soluble vitamins (A, D, E, K)
Dogs need vitamins to live, and they should get most of their vitamins from food. A balanced dog diet includes protein, fats, carbohydrates, vitamins, minerals, and water. Vitamins are very diverse and perform many different functions in a dog's body, such as the creation of DNA, bone development, blood clotting, normal eye function, and neurological function.
Fat-soluble vitamins require bile salts and fat to be absorbed in a dog's gut. There are four fat-soluble vitamins: Vitamins A, D, E, and K. Due to the way fat-soluble vitamins are stored and used by the body, they are at the highest risk for toxicity. Therefore, recommended allowances for fat-soluble vitamins do not need to be met daily and can be balanced over time, such as seven days, because the body stores the excess fat-soluble vitamins in the liver and fatty tissue.
Vitamin A is a fat-soluble vitamin that is required for normal vision, growth, reproduction, immune function, and maintenance of healthy epithelial tissue functions. It is also involved in the expression and regulation of many genes. Vitamin A is found in high amounts in wheatgrass and cod liver oil. However, it is important to note that too much vitamin A can cause dehydration, joint pain, and even harm your dog's blood vessels.
Vitamin D is another fat-soluble vitamin that plays a vital role in the retention and bone deposition of calcium and phosphorus. Its primary function is to enhance intestinal absorption and mobilization.
Vitamin E has eight isomeric forms, four of which are tocopherols, and the other four are tocotrienols. Overall, tocopherols are more bioavailable than tocotrienols, with α-Tocopherol being the most bioavailable form of Vitamin E. Tocopherol is found in moderate concentrations within raw seeds and nuts and, to a lesser extent, in leafy greens.
Vitamin K is a fat-soluble vitamin that plays a major role in protein synthesization, which is needed for blood coagulation and bone growth. Vitamin K1 (Phylloquinone) is abundant in leafy greens, while Vitamin K2 (Menaquinone) is produced by intestinal microflora found in the colon. Dogs can synthesize Vitamin K2 in the colon, so dietary supplementation is unnecessary for most pets. However, feeding leafy greens provides high amounts of Vitamin K and supports fiber fermentation in the colon.

Water-soluble vitamins
Dogs require a variety of vitamins to maintain their health and homeostasis. Vitamins are very diverse and perform many different functions in a dog's body, such as the creation of DNA, bone development, blood clotting, normal eye function, and neurological function.
Vitamins can be separated into two categories: fat-soluble and water-soluble. Water-soluble vitamins are not stored in the body and need to be consumed regularly in small amounts. They are essential for various bodily functions and are usually safe, even in large quantities, as any excess is excreted through urine.
B vitamins, for example, help with metabolism by breaking down carbohydrates and transforming them into energy. They also increase the absorption of other nutrients and stimulate a dog's appetite. Vitamin C is another water-soluble vitamin that dogs need for immune support. Unlike humans, dogs can produce their own vitamin C, so it is not considered an essential dietary component.
While water-soluble vitamins are generally safe, it is still important to provide them in appropriate amounts as part of a well-balanced diet. Consult a veterinarian to determine if your dog requires any specific supplements, especially if they are fed a homemade diet, as these may lack certain nutrients.

B vitamins
PEDIGREE® Multivitamins Immunity are chewable supplements that contain a blend of B vitamins, vitamin E, antioxidants, and beta-glucans. These vitamins support a dog's immune system, protect their cells, and increase their energy levels.
If you are feeding your dog a homemade diet, it is possible that they may need supplements to ensure they are getting enough vitamins. Dogs with certain medical conditions may also need vitamin supplementation, but this should be done under the supervision of a veterinarian.
It is important to note that dogs only need very small amounts of vitamins to complete their functions. Excess vitamins can lead to toxicity and other complications. Fat-soluble vitamins, in particular, can cause serious health problems and may even lead to death in dogs.
A balanced diet is key to ensuring your dog is getting the right amount of vitamins. Commercial dog food diets labelled "complete and balanced" are formulated to contain all the vitamins, minerals, and nutrients your dog needs.

Vitamin C
Dogs require a variety of vitamins to maintain their health and homeostasis. Vitamins are organic substances that are required in small amounts to sustain health and growth in all mammals, including dogs. Dogs can synthesize many vitamins through natural bodily processes.
Commercial dog food diets labelled "complete and balanced" are specially formulated to contain all the vitamins, minerals, and nutrients your dog needs. Foods catered toward different life stages, like puppy food, adult dog food, and senior dog food, contain different levels of certain vitamins, depending on the requirements of that life stage. Dogs fed an appropriate commercial diet should not require vitamin supplements unless recommended otherwise by a veterinarian. Dogs fed a homemade diet, on the other hand, may require supplements to ensure that they are getting enough vitamins with their meals.
If you are feeding your dog a homemade diet, it's possible that they may be lacking in iron, copper, calcium, and zinc. Before supplementing with any vitamin or mineral, consult with your veterinarian first to determine which supplement is missing from your dog's diet. Your vet may recommend supplementing your dog's diet with specific fruits and vegetables instead of vitamin supplements.

Vitamin supplements
Dogs require a variety of vitamins to stay healthy, including vitamins A, C, D, E, and K. Vitamins are essential for a dog's overall health and perform many different functions in their body, such as the creation of DNA, bone development, blood clotting, normal eye function, and neurological function.
Most dogs will get all the vitamins they need from eating a balanced diet of commercial dog food, which is specially formulated to contain all the necessary vitamins and minerals. Foods catered toward different life stages, like puppy food, adult dog food, and senior dog food, contain different levels of vitamins to meet the requirements of that particular life stage.
However, in some cases, vitamin supplements may be necessary. For example, if your dog has a medical condition, a vitamin deficiency, or a disease that affects their ability to absorb nutrients, your veterinarian may recommend supplements to ensure they get their daily recommended amount of vitamins. Dogs fed a homemade diet may also require supplements, as they may be lacking certain vitamins and minerals found in commercial dog food. It is important to consult your veterinarian before giving your dog any supplements, as too much of certain vitamins can be harmful, and human vitamins are not suitable for dogs.
If your dog does require supplements, there are chewable vitamins available that are designed to be palatable to dogs and can be given as a rewarding treat. It is important not to exceed the daily limit for your dog's weight and to ensure the vitamins are specifically made for dogs.
