About Dr. Tim's Dog Food

Premium All-Natural Pet Foods and Treats

Dr. Tim's offers honest, nutritionally sound kibble, wet foods, dietary supplements and freeze-dried treats designed for every life stage. The high-quality ingredients include low-ash protein along with the right blend of carbohydrates, fats and fibers to allow your pet to lead a healthy life.

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.


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.


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


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.


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

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.

The BEST for my pup.

I have tried different popular medications for my dog's sore joints but this is the one that works. It's soft as chewy and she likes it also. Shipping was fast and wonderful.

Seems to be helping

I have a 6 month old Boston puppy with luxating patellas, she has it in both hind legs. So far I've been using this product and she seems to be much better. Now it's only the 1 leg and that even seems to be getting better. I will continue using this product. This is my 3rd Boston terrier with luxating patellas. Luckily none of them ever needed surgery. The first 2 Bostons seemed to have healed and never had a problem ever again. So hopefully my pup will heal from this too. I also feed blue buffalo life protection small breed and it seems to be doing the trick.
