Did you know?
The protein bar industry grew from almost nothing in the 1980s to a multi-billion dollar global market. The first widely successful protein bar was the PowerBar introduced in 1986 by Brian Maxwell a marathon runner who wanted a convenient energy food for athletes. The industry has since splintered into hundreds of products targeting different fitness goals — most containing protein concentrations and artificial ingredients far beyond what dogs should consume.

What You Need to Know
Protein bars marketed to athletes consistently contain problematic ingredients for dogs. Sugar-free protein bars use xylitol or other artificial sweeteners. Many have chocolate coatings or chips. Some contain caffeine or guarana. Even those without these specific toxins contain protein concentrations far beyond dog dietary needs. Never give dogs protein bars under any circumstances.
