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.

  • This works!

    By on

    I bought 3 different food "enticements"; this one works. My chihuahua is suuuper picky and sprinkling just a little on top of her food does the trick.

  • Is there such a thing as dognip?

    By on

    My dogs love this stuff! I couldn’t imagine a life where I ate the same food for every single meal of my existence. But our furry friends are basically forced into that existence. A trade-off, I suppose, for not having to hunt for their food anymore. So I can’t blame them for being bored with their same-ol’ same-ol’ and not always wanting to eat it. But since I’ve been enhancing their food with this flavor booster there hasn’t been a single crumb left in either of their bowls.

  • Couldn't find a food that my dog liked

    By on

    Ever since we lost our older dog, our 11 year old hound mix just wouldn't eat regularly. Sometimes he would eat when the family sat down for dinner, but not all the time. I bought this flavor enhancer and now he eats his food on a usual schedule. He is not excited to eat like he used to be, but he is eating none the less.

  • Sooo good really works

    By on

    I had a standard poodle on a special awful diet that would never want to eat his food but this stuff was an amazing fix for him. I also have a German Shepherd that is just plain picky. I was feeding him fresh food mixed with kibble. Fresh food is about $10 per pound! I tried this and I was blown away that it worked.

  • Maybe for dogs

    By on

    My old cat wasn't remotely interested. Dogs might be more enticed if they like beef liver.

  • Not working well on my puppy

    By on

    She liked the taste of the product but if I put it over her kibbles, she would lick only Dr Tim’s, not kibbles. It worked only couple times. I don’t think the flavor is strong enough for my picky eater.

  • Appetite increase

    By on

    I purchased this product because one of my dogs is a very picky eater. She still would not eat her food when I put it on her food. It was not worth the price.

  • Makes a difference

    By on

    Have spoiled my dogs with canned food. This has for sure helped get them off of it. They like their food much better with a little extra flavor.
