Last month, we introduced you to the tiny terrier who could be crowned the world's smallest dog.
The 3-month-old terrier from Jarocin, Poland, weighs a measly 3.25 ounces. But that doesn't stop her from being incredibly excited -- ALL THE TIME.
Check out the furry ball of energy bounce over everything in the video above.
Clarification: We previously referred to the dog as Suni, but most news outlets are referring to her as Meysi (although there is still confusion over whether her name is Suni or Meysi).
