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.

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.

Spinal issues and stiff joints

He is 11 and 85lb. Mobility seemed to improve over time. This product has all items needed to help with his stiffness and mobility issues. Chewable and digestible.

Great product

Been using this for my 10 yr old dog for a long time. It’s like night and day difference when she walks and runs after now. She uses to have hip pain and this helped.

Chews for Zana

I believe they were helping but unfortunately we had to put my old friend down. Her cancer was advancing. My niece recommended them. She said they work good on her lab mix. She will get the rest of my jar.

This stuff works

My older shepherd has Fibrotic mythology and needs any extra love he can get from supplements. I’ve had him on these and CBD for months now and he seems more alive.

Stale product and horrible customer service

Received this item stale. There is no cover under the lid. The vitamins were all dried out and hard for my senior dogs to chew. I buy this product very often and have never experienced this problem. Reached out to customer service and they are absolutely no help. This was a complete waste of money this time around.

Joint supplement stale

This is the second order of this item that has arrived with the container internal seal loose and not sealed correctly. There is obviously a manufacturing problem as the containers are not properly sealed. Between my last two purchases of this item from Chewy, I bought the same formulation from a different supplier and the containers were sealed properly and the product fresh.

Saw Immediate results

Our 15 month old Pit tore his cruciate ligament & also had luxating patella. The vet said to try this product until surgery could be done. Otis hardly exhibited any signs of being in pain, just wouldn’t bear weight on leg & would quickly sit down. He kept to himself. Within 2 days of taking these chews, he was moving better, more cheerful disposition, more like the puppy he had been before his injury. 2 weeks post surgery the vet was amazed at his progress. Chews are easy to administer-eats them like it’s a treat.

For dog joint health

My 5 year-old German Shepard/Lab mix has been on joint support supplements since she was 9 months old. It was recommended by my vet to prevent hip problems later on. I saved $20 a bottle being on-line and it is the very same stuff.
