Why should I include vitamins & supplements in my pet’s diet?

Most commercial pet foods include baseline vitamins and nutrients, but some may not have the adequate amount to suit your pet’s exact health needs. Like in humans, vitamins and supplements can help support your pet’s long-term health, regulating everything from digestion to muscle growth. Consult your veterinarian to determine the best vitamins and supplements for your furry friend.

How often should I give this supplement to my pet?

It is recommended to give the suggested dosage based off your pet’s weight. Please refer to the Feeding Instructions tab and consult with your veterinarian for more information.

Is this supplement safe to use with the medication my pet is currently taking?

Premium All-Natural Pet Foods and Treats

Foods Made to Match Your Pet

When shopping for Dr. Tim's pet foods, you'll notice the labeling indicates an activity level. That's because they're made to complement your pet's lifestyle, with ideal ratios of protein, fat, carbohydrates and fibers to help her thrive. You'll find recipes that are specially formulated for active pets, low-key pets, extreme athletes and those in need of weight management.


ACTIVE: This food is designed for the sporting dog that's active more days than not—dogs who hunt or jog every day, herding dogs, police dogs and the like. It's made for maximum digestion, an important consideration for these dogs that's often overlooked. Protein types and levels, fat types and levels, and fiber sources are formulated to maximize performance and recovery.

Casual Lifestyle

CASUAL LIFESTYLE: This is a diet intended for the dog who lives a normal lifestyle—sleeping on the couch, running around the backyard or going on car rides, walks or hikes and basically just living the good life. The only regular exercise she might get is tail wagging when she sees you at the end of the day, or some loving nose nudges.

Extreme Athletes

EXTREME ATHLETES: This food is for dogs who are serious about working nearly every day for long periods of time, such as sled dogs and dogs who hunt most days of the season. It's extremely high in fat, high in protein and low in carbs, with the highest levels of essential omega-3 fatty acids and loads of antioxidants. Performance, endurance and recovery are all enhanced.

Weight Management

WEIGHT MANAGEMENT: This diet is intended for the dog who has put on some extra weight. High protein allows your overweight dog to be more active, and moderate fat allows her to feel satiated so she doesn't beg—an essential part of the equation. The omega-3 and antioxidant profiles help reduce the inflammatory stress that's prevalent in an overweight dog, too.

Treats That Deliver

Treats That Deliver

Dr. Tim's freeze-dried treats are formulated for both cats and dogs—perfect for multipet households. They're made from 100% real, USDA-inspected meats from Wisconsin. And since they're freeze-dried, you can give your pet all the nutrition and flavor of raw meat without any of the mess or inconvenience.

Top It Off With Nutrition

Dr. Tim's Flavor Booster is made of 100% real, USDA-inspected beef liver powder from Wisconsin that is freeze-dried to maintain more nutrients. It's perfect for use as a food topper to encourage pets to eat and enjoy their meals, which makes it a great choice for finicky dogs or those who are ill or tired of the same formula.

About Dr. Tim's

As a veterinarian and accomplished musher, Dr. Tim Hunt understood his dogs' need for a food that promotes stamina, endurance and performance through proper digestion. Armed with a cement mixer, a cache of ideas, and an aversion for other diets on the market, Dr. Tim took to his Michigan garage on a mission to formulate a food that replicated a natural, wild diet for his Alaskan Huskies. Today, Dr. Tim's focus has since expanded to bring an honest, nutritionally sound food—sourced only from North America's highest quality ingredients—to every dog.
