The Best Nutritional Supplements For Dogs

Keeping your dog healthy is a big part of being a pet owner. While your pup will get the bulk of their nutrients from their food, you may need to supplement their diet if they're dealing with a health issue or eating a special diet. When this happens, you want to be sure you choose the right products to keep them healthy and happy. With so many supplements available for dogs, knowing which one to choose can be a difficult task. To help you with your search, we've rounded up some of the best the market has to offer.

What to Look For 

We recommend keeping the following things in mind when shopping for supplements for your dog: Is it a reputable brand that uses high-quality ingredients? Does the supplement address the problem your dog is experiencing? Do they come in a pill form, chews, or an easy mix-in formula? Our favorite was the 8-in-1 multivitamin bites from Zesty Paws, which contain all the vitamins and minerals needed to help keep your pup healthy. We also really liked the all-in-one supplement from NaturVet, which provides nutrients to support your pet’s joint, skin, and coat health.

What are the best supplements for older dogs?

As dogs age, they often develop problems such as arthritis and cognitive dysfunction. After talking to your vet, they may recommend supplementing your pooch’s diet with vitamins and minerals that can help these conditions. For example, omega-3s and glucosamine can be helpful for joint problems older dogs experience, while blends targeted to support cognitive functions can help with doggy dementia.

Do dogs need probiotics?

When dogs are dealing with digestive issues like diarrhea, they may need to take probiotics. Like the probiotics formulated for humans, the particular strain will determine its benefits. So, you should look for a strain that treats the symptoms your pup is experiencing. If your dog is healthy, there’s usually no need to add probiotics to their diet.
