MADISON, Wis. -

Sixty-four puppies and young adult dogs are looking for new homes after being brought to Madison from overcrowded shelters in North Carolina and Mississippi, according to the Dane County Humane Society.

DCHS spokeswoman Marissa DeGroot said as of 5 p.m. Thursday, 25 of the pups had already been adopted.

The puppies will be available for adoption at the DCHS through the PetSmart Charities Rescue Waggin’ program, officials said.

"We are so grateful to live in a community that has opened their doors to animals in need from across the country," DeGroot said in a release. "We are happy we are able to aid shelters experiencing extreme overcrowding and thankful for the support of PetSmart Charities in helping transport these puppies to Wisconsin to help find their new forever homes."

The dogs range in age from 8 weeks to 3 years. They arrived in Madison on Wednesday afternoon, and were available for adoption beginning Thursday, officials said.

The majority of the adoption fees for the dogs will be $450, and dogs will be able to go home after being spayed or neutered, according to the release.

DeGroot said the adoption fees cover the cost of spay or neuter surgery and vaccinations. It also helps the shelter, which is an "adoption-guarantee" facility, care for all homeless animals in need that enter DCHS doors. An adoption guarantee shelter keeps any healthy or treatable animal at the shelter until a forever home is found, DeGroot said.
