Wolf Pup 1's favorite activities after getting to Ely's International Wolf Center were dragging his stuffed moose around his enclosure, and taking balsam fir branches from the walls.
His brother – Wolf Pup 2 – has taken to howling in his sleep and digging to discover new things. Wolf Pup 1 has also started exhibiting some stalking and predatory behavior, according to the center. Wolf Pup 2 hasn't quite done so yet.
And you can help name these adorable, numbered pups.
The International Wolf Center is asking the public to submit their suggestions in a wolf pup naming contest, and hoping people will keep these personality quirks in mind while submitting ideas.
The International Wolf Center wants participants to observe the wolf pups' behavior before submitting name ideas. They bring them out four times a day for live public programs. If you can't make it up to Ely, you can watch them any time on the live pup streaming cam here.
"By watching them play and explore, people can get an idea of their personalities to come up with creative and memorable names," said executive director Rob Schultz in a news release.
Name submissions will be accepted here until midnight on Friday, June 24. Then the names will be narrowed down to the top three for each pup, and final voting will take place from June 28-July 1.
A prize package worth over $300 will be awarded to those who submitted the winning names. The package includes a one-year membership to the International Wolf Center, two tickets to see the pups in person, and a variety of "fun wolf-themed merchandise."
