Northwestern wolves tend to be a bit larger, said Lori Schmidt, an International Wolf Center curator.
The pups, who arrived at a few pounds a piece, have been growing up to a half pound a day, she said.When they reach 35 to 40 pounds, they will be integrated with the adult wolves, likely at the beginning of August.
The introduction into the exhibit pack must occur when the pups are large enough, but not too big to test the older animal's weaknesses, Schmidt said.

"You'll see nannies in there sleeping," Schmidt said."This is a critical bonding period."
Unlike domesticated dogs, wolves retain genes selected for survival in the wild, and they are not prone to accepting humans.But they will bond with people when socialized at an early age.
Since the pups will remain in captivity -- living up to 16 years as opposed to eight to 10 in the wild -- and will require interactions with wolf center staff and vets, it's especially important for the wolves to become accustomed to humans, Schmidt said.
They must also learn to accept various sounds and activities, such as raking in their enclosure.They will also be viewed and photographed by thousands of visitors through the windows in the center's viewing area."The glass isn't tinted" nor soundproofed, Schmidt said.
The pups already have differing personalities, she said.

Attila was showing headshakes "before he could walk," Schmidt said.
At 25 days of age, the pups demonstrated play bows for a group of onlookers prior to an open house event.And Red Paw has been pouncing on a toy stuffed moose in the nursery.
The adult wolves know the pups are around as well and have been howling to them, Schmidt said.Both female and male wolves produce a nurturing hormone, she said.
When the 2004 litter was introduced, the adults "regurgitated for them," licked the pups, and protected and parented them, she said.
During the upcoming introduction, one adult at a time will be introduced to the pups in "the security of pup pen," which will "make them much less nervous."
But first, the pups will share a protected fence line with adults, so they can sniff each other.
While the pups initially displayed some natural "fear avoidance" traits, they are bonding quite well to their human caregivers, Schmidt said.
"The pups are showing some very strong associative bonds with the human handlers," Schmidt wrote on a daily online pup log.
"The socialization process is critical for wolf care staff to handle adult wolves," she wrote.
