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.

did not help

Tried this product after the Lubrisyn HA for a dog with a doggie knee "replacement". She improved on the Lurbrisyn HA but didn't like the taste. Dr. Tim's tastes somewhat better for her but she is back to hopping on 3 legs on this supplement. Maybe it works better other conditions. 70 lb dog on 2 chews a day.

Good Taste

My fur baby likes the taste, so she thinks she is getting a treat. Makes it easy to give and I am hoping the rewards will be just as good. Too soon to tell if these are making a difference or not.

My Setter enjoys these

Gemma appears more comfortable since we started using these over a year ago. She is still amazingly active for 13 y.o. Thanks for developing this product Dr. Tim!

Seems to help my dogs mobility

Rocky is a young dog again!

My 12-year-old golden Rottie mix was so sore he couldn't walk up the stairs anymore, so a vet friend recommended I look at supplements. I tried the ones she suggested first, but my dog was not interested in them at all and hated the taste. These, though, he loves, so much that I sometimes use them as pill pockets when he has medications he needs to take! Plus, he is back to taking 2 mile walks and being a young boy. These have been a godsend! One word to the wise - our other dogs try to get into them because they taste so good, and an overdose on arthritis supplements can hurt them, so keep them in a cabinet!!

The product was perfect but I am concerned about product inventory

The product was what I wanted but I didn't rate it a 5 star because I am concerned about your product inventory. When I ordered this I tried to reorder dog food I had purchased in the past. It was not available and to date I hve nt received notification it was back in stock

So far so good

My vet recommended these for my 4 year old English lab. They have not made her sick in anyway. She is noticeably bouncier and energetic. She used to limp really bad after playing fetch for a short period of time, now she rarely shows any signs of limping.
