MARIN COUNTY, Calif. -- The Marin Humane Society on Friday will become the temporary home for about 100 small breed dogs that were among 800 dogs and puppies seized from a mobile home in Southern Arizona Wednesday, NBC11's Staci Ciauri reported.

An elderly couple apparently overwhelmed trying to care for the animals were breeding the dogs for sale, officials said. Authorities at the Southern Arizona Humane Society described the living conditions in the triple-wide mobile home as one of the worst they've ever seen.

SLIDESHOW: Confiscated Dogs Coming To Marin

Most of the dogs coming to Marin are teacup Chihuahuas and are part of what the Marin Humane Society is calling Operation Tiny Teacup. Pomeranians and terriers are also among the group.

"The Southern Arizona Humane Society is a small shelter with very limited housing and resources to handle the magnitude of this case," MHS animal care director Kim Lanham-Snyder said. "We are dedicated to helping our friends in Tucson and anticipate a great response from our dog-loving Bay Area community."

The rescued dogs need medical care, spay and neuter surgeries, and loving homes, the Humane Society said. The dogs will stay with foster families and at the shelter in Novato for the next two weeks or so before they are ready for adoption.

Animal care workers said there had been strong interest from the public throughout the day Friday from people hoping to adopt.

In addition to the dogs, police also recovered three dozen birds from the home.

Ciauri reported that two of the dogs died in Arizona.

Marin Humane Society officials are transporting the dogs by cargo van and were expected to arrive in Novato on Friday night.

Shelter staffers said they are surprised that most of the dogs are in good condition, considering the inhumane treatment they received.
