What Customers Have Said

Verified Buyers Across the U.S.
Even my Picky Pup LOVES these

"I hired a dog trainer who was surprised by my dog's lack of interest in treats, so you can imagine my shock when, years later, my pup excitedly ate the Bison Liver Yummies right out of my hand!"

- Johnny K.

Pup Approved Treats

Truly impressed by this brand and both their treats and chew toys. My pup can't get enough...he'll literally pick up his toys and bring them to me in hopes of me rewarding him with these bison treats. Love that they're nutritious and not full of any fillers or other junk!

- Ben A.

The Perfect Treat

"These bison liver treats are amazing! They already come in small, bite-sized pieces, which makes them perfect for training sessions. My dog absolutely loves them--he's super motivated whenever I bring out the bag."

The Trouble with Dog Treats

We all want to spoil our dogs, but treats often get a shrug—aren’t they all the same? Not quite. Most are stuffed with empty calories, additives, and fillers that drag down health. Mumbies Yummies flip the script: freeze-dried bison liver, nature’s superfood, bursting with vitamins and minerals. One ingredient, big flavor—treat time’s a win again.

Diet is the Key to Longevity

What your dog eats shapes their years. Treats heavy on bacon, peanut butter, or cheese skew it with fats and carbs—fillers pad, preservatives fade nutrients, and “natural” tags can cloak vitality-draining junk. The result? Dull days and creaky steps. Yummies fuel the fix: freeze-dried bison liver loads their diet with essentials, paving the way for a longer, stronger life.

Dogs Go Wild for These Treats!

No Stink. No Mess. Dogs Love 'Em.

Without Any Tricks, Scents, Or Flavorings Added.

5 Reasons Yummies Are the Best

1. PACKED WITH NUTRIENTS

Most meat treats skimp on vitamins and pile on calories. Yummies flip that—bison liver slashes the fluff and delivers essentials like antioxidants that sharpen eyes, boost immunity, and support brain health.

2. PURELY SIMPLE

Beef, dairy, chicken, wheat—common culprits in dog allergies—fill typical treats. Yummies? One ingredient: bison liver. No fillers, no artificial junk, just clean goodness.

3. PRESERVATIVE-FREE POWER

Dyes and preservatives in treats can spark health issues, while overprocessed options strip nutrients. Our freeze-dried bison keeps 97% of its punch*—NASA trusts this method for astronauts; your dog deserves it too.

4. GRASS FED, ALL-AMERICAN

Sourced from humane Minnesota and South Dakota ranches, our bison graze naturally, with supplemental feed only when weather demands. We buy excess organ meat from farmers supplying top global restaurants—quality you can feel good about.

5. SAVING DOGS, ONE CHEW AT A TIME

Shelter euthanasia spikes from shortages of food and supplies. When you shop with Mumbies, a portion of proceeds supports under-resourced rescues, fueling our dream: a self-sustaining sanctuary for dogs in need.
