JOHNSON CITY, Tenn. -

The Washington County-Johnson City Animal Control Center welcomed a steady stream of pet-lovers through their doors Wednesday.

This comes less than 48 hours after staff members say someone dumped 20 malnourished dogs outside their shelter.

News 5 spoke with center's director, Debbie Dobbs, who made the alarming discovery. "It think I've answered a little more than 45 phone calls since 10:30 this morning, and it's 12:30 p.m. right now. People are concerned that these animals get a home," said Dobbs.

She tells me the rush is a far cry from Tuesday’s discovery. Dobbs says she came to work Tuesday morning and found the shelter's drop off box full of small pets with no clue as to who left them there. "They were cold they were all shaking. They were friendly, which means at one time or another whoever had them did care for them. I can't say that someone didn't care for them. I'm saying someone either got overwhelmed or just couldn't handle it anymore. They smelled very bad," said Dobbs.

Dobbs tells us she and her staff spent the rest of day evaluating, vaccinating, and feeding the dogs, so people like Wayne and Tammy Smith can give them a new home. "She's a terrier mix, she so scared and cold," Tammy said while playing with one of the puppies. "You can tell she just needs a lot of love and attention."

Tammy says she still thinking of a new name for her new friend. "I just have to get her and see what [name] feels right," she said.

Dobbs tells us she appreciates donations to help pay for medicine.

We learned that after the dogs arrived, more than 100 cats and dogs were in the shelter Wednesday.
