Have you wondered if your senior dog would benefit from taking vitamins and/or supplements? Does your pet companion have a medical condition that requires he take extra supplements or vitamins? Can you give your dog too many vitamins? This article is a guide to help answer your questions. We’ll take a look at vitamins and supplements for older dogs, how to know if your dog needs supplements, and then take a look at several vitamin supplements to help you choose one for your senior furry pal.

What are Dog Vitamins?

Just like us, our canine companions need the right mix of vitamins and minerals to stay healthy. We humans tend to take vitamins on a regular basis, and believe our canine friends should, too. So, just what are vitamins?

Vitamins are organic compounds and essential nutrients that humans and animals need to survive and thrive. Humans and our pet companions (along with other animals) can’t make these substances within our bodies, so we have get our nutrients from the foods we eat.

Essential nutrients enable many functions within our bodies—everything from regulating cell and tissue growth to supporting the nervous system and organs to work correctly. Vitamins also help with the growth and development of the fetus, childhood/puppyhood development and ongoing adult health. Certain medical conditions in humans and animals also require specific nutrients in order to maintain health or to heal from disease and infections, etc.

As you can see, vitamins are essential for us and our pet companions. Without proper nutrition we quickly become weak and more susceptible to illness and possibly even death.

Do Dogs Need Vitamin Supplements?

Your dog may be getting all the vitamins he needs in his dog food. Most commercial dog foods include a label that includes the phrase “complete and balanced,” meaning the food contains all the nutrients a dog needs on a daily basis. The nutritional requirements your dog needs typically vary by age—puppies have different nutritional requirements than adults dogs, while senior dogs require a different balance of nutrients than their younger adult canine friends.

Your fur baby is more than likely getting the vitamins he requires to stay healthy and active, as long as you’re feeding him the proper diet for his life stage

On the other hand, dogs who are on a homemade diet may need vitamin supplementation, as homemade diet may not include all the necessary vitamins your pet needs.

Are There Risks with Giving My Dog Vitamins?

Yes, there are some risks involved with giving your fur baby vitamins. An overdose of certain vitamins can upset your pet’s health. Vitamin toxicity (vitamin overdose) is a serious condition and can cause everything from liver problems to problems with the nervous system and even death.

So, it pays to be careful with any vitamin supplements you’re giving your pup. Pay attention to daily recommended nutritional values and don’t go over these, unless directed to by your veterinarian.

Why Would My Senior Dog Need Vitamins?

Some older dogs need daily vitamin supplements if they’re on a homemade diet, but there are other instances where your fur baby may need to take vitamins. A dog may need supplements in these cases:

Dogs in these cases can benefit from the nutrients provided by vitamins. However, it’s a good idea to check with your veterinarian before giving your furry canine friend any type of vitamin supplement.

Vitamins for Older Dogs

Dogs go through many physical changes as they age, just as we do. Our furry canine companions have special nutritional requirements when they reach their senior years. Your pet may need a different balance of nutrients as he ages, with specific vitamins and minerals aimed at any health issues he may have:

These are only a few of the conditions your older fur baby can face as he ages.

Looking for the right vitamin supplements can take time and research, but the health of your pet is worth all the extra effort to find the optimal vitamin supplement to give him better quality of life in his elder years

Which Vitamin Supplement Should My Dog Have?

This will depend on your dog’s diet, his age and the state of his health. The best judge of whether or not your pet needs vitamins will be your veterinarian. They will know your dog inside and out, be familiar with his medical conditions, diet, etc. Your vet is your best guide in this instance.

If your vet recommends vitamins for your pup, they may make a recommendation on the brand and the daily requirement for each vitamin your dog needs. However, your vet may just offer a general idea about the need for multivitamin, without naming a specific brand. If you’re in this situation, we’ve got information to help you find the best multivitamins for your fur baby!
