5 Ingredients in Dog Treats That Could Be Shortening Your Dogs Life Span

Most dog parents are shocked when they learn what’s actually inside some of the most popular treats on the market. While the front of the bag might say “wholesome” or “made with real meat,” the back often tells a very different story. If you’re trying to make better choices for your pup, here are five ingredients worth avoiding and what to look for instead.

1. BHA and BHT

Used to extend shelf life, these synthetic preservatives have been linked to cancer and organ damage in multiple studies. While banned in parts of Europe, they’re still approved in U.S. pet products. That’s why more pet parents are looking for treat options that use safer preservation methods—like freeze-drying—rather than relying on chemical additives.

2. Meat By-Products

This vague term can include everything from beaks and feet to fatty tissue and low-grade organ meat. It’s a cost-cutting move, not a health-conscious one. Instead of guessing what’s inside your dog’s treats, opt for brands that keep things simple and transparent. Single-ingredient treats made from recognizable whole foods are a great place to start.

3. Artificial Colors

Bright red or yellow treats might catch your eye but your dog doesn’t care what color their snack is. Dyes like Red 40 and Yellow 5 have been associated with allergic reactions and even behavioral changes. Clean-label treats skip the artificial stuff altogether, focusing on real ingredients that taste and smell great naturally.

4. Corn Syrup and Added Sugars

Many treats sneak in sugar to make their product more palatable but added sweeteners can contribute to obesity, inflammation, and dental problems. Dogs don’t need sugar to enjoy a treat. In fact, many will go wild for freeze-dried meat with nothing added. Real flavor, no sweeteners required.

5. Wheat and Corn

These grains are often used as inexpensive fillers, but they’re also common allergens. Dogs with itchy skin, frequent ear infections, or upset stomachs might actually be reacting to these hidden ingredients. Grain-free treats made from just one source of animal protein can be easier on digestion and better suited for sensitive pups.

What to Look for Instead

If reading this list made you flip your treat bag over—good. You’re doing your homework, and your dog deserves that.
