How Much Should I Feed My Mixed Breed Dog?

Feeding your dog the right amount of food isn’t just about filling a bowl—it’s one of the most important parts of keeping them healthy. For mixed breed dogs, who come in all shapes, sizes, and energy levels, figuring out how much to feed can feel a little tricky. There’s no one-size-fits-all answer, but with a few basic guidelines and some observation, you can easily find the right portion size for your pup.

In this post, we’ll cover feeding recommendations by weight and activity level, plus how to adjust over time as your dog grows or their needs change.

How Portion Size Is Usually Calculated

Most dog food bags include a feeding chart based on your dog’s weight. That’s a helpful starting point—but it’s just that: a starting point. These charts often overestimate or underestimate your dog’s needs, especially if they’re unusually active (or super chill).

A better method is to look at the calories your dog needs each day, measured in kilocalories (kcal). This info is usually listed on your dog food packaging, and many brands also provide calorie counts per cup. From there, you can do a little math to portion out meals more precisely.

If you’re not into math, don’t worry—we’ve got some simple guidelines below to get you in the right ballpark.

Feeding Guidelines by Weight

Here are general daily calorie needs for adult dogs based on weight and an average activity level. Keep in mind these numbers can vary depending on your dog’s body type and metabolism.

Small Dogs (under 20 lbs)

Calories/day: 300–500
These dogs need less food overall, but because of their small size, portion control is especially important. A few extra bites can lead to weight gain fast.

Medium Dogs (20–50 lbs)

Calories/day: 600–900
This includes a wide range of mixed breeds—from Beagle mixes to medium-sized terriers. Most average about 2–2.5 cups of dry food per day, depending on the brand.

Large Dogs (50–90 lbs)

Calories/day: 1,000–1,400
Big dogs burn more fuel, especially if they’re active. Think Lab or Shepherd mixes. Pay attention to their muscle mass—leaner dogs may need more food than stockier ones of the same weight.

Extra-Large Dogs (90+ lbs)

Calories/day: 1,500+
If your mixed breed has giant breed genetics (like a Mastiff or Great Dane), they’ll need a lot of food—often spread out over 2–3 meals a day to help with digestion.

How Activity Level Changes Your Dog’s Needs

Just like people, dogs with different lifestyles need different amounts of fuel.

• Low-energy dogs (senior pups or couch potatoes) might need up to 20% less than average.
• Moderately active dogs (daily walks and some play) usually do well on standard calorie estimates.
• High-energy dogs (those who run, herd, or do agility) may need 20–30% more calories than average.

Keep an eye on your dog’s body condition and energy levels. You should be able to feel (but not see) their ribs, and they should have a visible waist when viewed from above.

How to Adjust Over Time

Your dog’s needs won’t stay the same forever. Here are a few reasons you might need to adjust their food intake:

• Growing up: Puppies need more food (and more meals) than adults.
• Getting older: Senior dogs often have slower metabolisms.
• Seasonal changes: Some dogs are less active in the winter.
• Lifestyle shifts: More hikes? New baby? Change in schedule? All can affect calorie needs.
• Spay/neuter status: Altered dogs sometimes require slightly fewer calories.

A good rule of thumb: reassess your dog’s weight and body condition every few months, especially after any big changes.

What About Mixed Breed Puppies?

Puppies burn through calories quickly and need more frequent meals.

• Under 6 months: Feed 3–4 small meals per day
• 6 months and up: Transition to 2 meals a day
• 1 year: Most mixed breed dogs are ready for adult feeding guidelines

Make sure to feed a puppy-formulated food that supports healthy growth, and avoid overfeeding—especially for large breed mixes. Too-fast growth can stress their joints.

Real-Life Feeding Examples

Sometimes it helps to hear what works for other mixed breed owners:

“My 35-lb Lab/Beagle mix eats about 1.5 cups of kibble per day, split into two meals. We adjust slightly in the winter when she’s less active.”
— Danielle, dog mom in Colorado

“Our Border Collie mix runs with us every morning. She needs almost double what the bag says—about 1,200 calories a day—just to keep weight on.”
— Mike, dog dad in Oregon

Every dog is different, so don’t be afraid to experiment (within reason) and make small adjustments until your dog looks and feels their best.

Common Feeding Mistakes to Avoid

• Free feeding (leaving food out all day) can lead to overeating.
• Following the bag exactly without considering your dog’s unique needs.
• Too many treats—they add calories fast! Try low-cal training treats or veggies.
• Not adjusting portions after lifestyle or age changes.

Conclusion: Watch the Dog, Not Just the Bowl

Feeding your mixed breed dog isn’t about strict numbers—it’s about balance. Start with general guidelines based on weight and activity, and adjust from there based on how your dog looks, feels, and acts. A healthy weight, shiny coat, and steady energy are great signs you’re on the right track.

And remember, if you’re ever unsure, your vet is your best resource for personalized advice.

FAQ

How many times a day should I feed my mixed breed dog?
Most adult dogs do well on two meals a day, but some prefer smaller, more frequent feedings—especially if they’re prone to digestive issues.

Should I feed based on weight or breed?
Weight and energy level are more helpful than breed mix alone. Mixed breeds can vary a lot even within the same weight class.

My dog always acts hungry—am I feeding enough?
Some dogs just love food! Our dog Jinji will go sit by her bowl asking for food any time we’re in the kitchen. Try adding fiber (like pumpkin or green beans) or switching to a food with higher protein to help them feel fuller. If your dog is losing weight or seems obsessed with food, check with your vet.
