FAQs

Should pets take vitamins?

Essential vitamins and minerals help maintain your pet’s healthy coat, strong bones and teeth, joint flexibility, and cognitive function. Joint supplements for dogs may be necessary for older pups with arthritic hips. However, whether or not you should supplement a pet's diet with dog vitamins (or cat vitamins) is a question best answered by your veterinarian.


First, be sure your pet receives a complete and balanced diet. Pet vitamins or supplements may be needed if your dog’s diet comes from homemade rather than commercially processed dog food. If you detect any problems, such as a poor appetite or reduced energy — especially for a dog with a typically active lifestyle — it is recommended that you consult your vet before adding vitamins or other supplements to their diet.


Be sure to schedule annual wellness exams. That way your vet can assess the growth and development of your four-legged companion and address any health issues.


Can dogs take human vitamins?

Simply put, dog vitamins are for dogs. Just as human vitamins are made for people and our particular constitutions, pet vitamins and supplements are specially formulated to meet the nutritional health needs of animals. It’s best not to mix the two.


A major reason dogs (and cats) should not take human vitamins is because the dosage is different. An overdose of calcium for a large breed dog, for example, can actually contribute to skeletal problems. Too much vitamin D may harm muscles and bones, while an excess of vitamin A can cause, rather than alleviate, joint pain.


Most vet-prescribed or over-the-counter formulas are sold in the form of chewable capsules or powder sprinkled on food for easier digestion. Whether you want to find the best multivitamin or joint supplements for dogs, look for natural supplements without artificial flavors and other harmful ingredients.


Always talk to your vet about your pet’s health first and ask how it might benefit from a particular supplement.


What are the most important vitamins for dogs?

In addition to protein, healthy fats, carbohydrates, and minerals, dog vitamins are an essential part of your pup’s nutritional requirements. The most important vitamins for dogs are vitamins A, B, C, D, and E — easy to remember in alphabetical order.


At a glance, here’s what each vitamin contributes to canine health:


  • Vitamin A for cell growth, immune function, and eye health
  • B-complex vitamins for healthy blood cells, skin, and nervous system
  • Vitamin C for cognitive function and reducing inflammation
  • Vitamin D for healthy bones and muscles
  • Vitamin E for fat metabolism and reproductive health

In addition, you’ll find a variety of herbal supplements for dogs. Select products are made with active natural ingredients, instead of synthetic nutrients, to treat your pet’s condition, such as valerian root, ginger, and chamomile to calm anxiety or stress; turmeric and glucosamine, a natural compound, to reduce hip and joint inflammation; and fish oil to alleviate skin allergies.


How much of each vitamin and other essential nutrients your dog needs will vary, depending on their life stage, activity level, genetics, and any health issues. As always, consult your vet.
