Yes dogs can safely eat beef jerky that is made for humans.
The beef jerky that is made for humans is made of beef and it's okay to feed your dog some human beef jerky.
Actually the beef jerky that humans eat is likely much healthier for your dog than dog beef jerky is because dog beef jerky is made using other non natural ingredients.
But beef jerky made for human consumption uses natural ingredients which make it safe for humans to eat as well as dogs to eat.
Almost anything a human can eat a dog can eat as well and even cats and other animals.
My dog eats a stick of beef jerky that is made for humans every few days as a treat and so does my cat.
Both my dog and cat love human beef jerky and will not eat the dog jerky because they don't like the taste or smell I guess.
