You should introduce Hark gradually over 7–10 days—start with 25% Hark and 75% their old food, slowly increasing to 100% Hark.

Depending on your dog's size and appetite, a bag of Hark typically lasts between 2–6 weeks. When you place your first order, we'll ask for your dog's weight and activity level, and will recommend the best order size.

Hark is more nutrient-dense than most food for dogs, so you may notice you're feeding less by volume than with other foods.

Each cup of Hark delivers 610–650 calories, depending on the recipe—that’s nearly double the calorie density of many conventional dog foods like kibble, which often contain fillers and loq quality ingredients that don't add nutrient value. So while the bowl might look smaller, it’s packed with the same (or better) nutrition your dog needs to thrive.

Use your dog’s body as a guide—if ribs are hard to feel or they're gaining quickly, scale back. If they’re losing weight or acting hungry, feed a bit more.

Hark is nutrient-dense, so you’ll likely feed less by volume than you’re used to. Many traditional feeding charts overshoot it. They assume your dog isn’t getting treats, isn't carrying a few extra pounds, and needs more calories than they actually do. This is part of why 59% of dogs in the US are overweight or obese, according to the Association for Pet Obesity Prevention.

With Hark, you get smarter portions that match how real dogs eat. Start with the feeding chart on the bag and adjust based on your dog’s energy, build, and activity.

Absolutely. Puppies are growing fast—building bones, brains, and boundless energy—so they need food that keeps up. That’s why we recommend starting with our 100% Human-Grade Chicken recipe, which is naturally a bit higher in fat, making it a great choice for growing pups who need extra fuel.

Even large breed puppies (who will weigh 70+ lbs as adults) can enjoy Hark from day one. Our recipes are formulated with carefully balanced calcium and phosphorus to support healthy bone development during those crucial growth months.

Most dogs reach adulthood between 8–24 months. Smaller breeds tend to mature closer to 12 months, while giant breeds can take up to two years. Once your puppy is full-grown, you can stick with their favorite recipe—or switch things up to a recipe with less fat like our Beef recipe, based on their activity level and preferences.

Any Hark recipe can work—choose based on your dog’s energy level, size, and preferences.

Chicken tends to be easiest on older tummies—lower in fat, easier to chew, and easy to digest.

Hark’s Chicken recipe is slightly higher in calories and healthy fats—great for dogs needing a little extra padding.

We support many rescue organizations and when people adopt through Hark, we give them their first month of food for free. We generally recommend our chicken recipe to underweight shelter dogs.
