This Adorable Puppy Caught On Quick!
In the early 1900s, Russian doctor Ivan Pavlov would ring a bell and then feed his dogs. Slowly, the dogs began to salivate at the sound of the bell instead of at the food. It seems this dog owner did the reverse: meet Maddie. She’s still just a pup, but this dachshund has learned a really cool trick. Ringing a bell will give her a treat! I have a gut feeling that bell is never going to stop ringing.
