EAST ROCHESTER, N.Y. -- The saga of Tessa the goldendoodle continues, as a Sodus woman now stands accused of selling the dog that last week went missing from a Penfield kennel where she worked.

Cassandra Blake, 23, is charged with grand larceny and stealing a companion animal. She was arraigned Wednesday in East Rochester.

Tessa disappeared from TheraVet Acres Rehabilitation and Fitness on Friday. Her owners then received 10 fake messages, some saying their dog was dead.

A Canandaigua woman who saw the story on the news got suspicious and contacted the kennel. She says she recently bought the dog for $400. She then brought the dog back to the kennel, where it was reunited with its rightful owners.

Blake was standing by Tuesday as Tessa and her family reunited.

Blake was arrested hours later, at the end of her shift, and her car was on Wednesday still parked in the TheraVet lot.

TheraVet Acres owner Dana Browne says Blake's was a well thought-out plan. He believes Blake placed the ad on Craigslist last Wednesday, and the dog went missing two nights later when staff members were at a Halloween party.

"Right at the end of the shift, she was the last one here, so she took the dog, probably walked right out, put her in the car," Browne said.

Browne says it you take a real close look at the car, nose prints left by Tessa were still on the window.

The news is still fresh and tough to swallow for Nicole Vanzo, who worked side-by-side with Blake.

"It's just difficult to hear that, you know, she was betraying our trust and she was betraying every single owners trust that, you know, bring their dogs here," Vanzo said.

The woman who returned the animal already has the heartfelt thanks of everyone here, and stands to gain more.

"She's going to get a substantial reward from TheraVet much more than, significantly much more than what she's out and there's a goldendoodle rescue group that's offered to work with her if she's interested in going at this again," Browne said.

"It's difficult, first putting the pieced together and then trying to understand why somebody would even do something like this," Tessa's owner Ed Turkowski said. "Why is it desperation? Why would they consider doing this knowing full well what they are doing and that that animal belonged to somebody else. I say animal, but they're our kids, they're our kids and we love 'em."
