UXBRIDGE, MA (WPRI/CNN) - On Sunday, two kayakers making their way down Blackstone River in Uxbridge heard whimpering coming from a bag in the water.
The bag was tied shut, with six puppies inside.
Kevin Sullivan, a regional animal control officer, said that they were "very sweet dogs."
Sullivan said the runt of the litter was in the worst shape.
"He actually had quite of bit of water in his lungs," Said Sullivan. "Up until this morning, he was still pushing mud out of his nose."
All six puppies are doing much better, according to Sullivan.
Uxbridge police said their focus is on who did this to the puppies.
"It's unconscionable," said Chief Jeffrey Lourie. "You can't imagine … going through my head as a police officer of 29 years … someone would do that - would take six newborn puppies and discard them in a body of water to their death - it's unconscionable"
The chief said they're looking for a white man who was riding a mountain bike in the area around noon on Sunday.
"They are reviewing video as we speak," said Lourie.
Sullivan said offers to adopt the puppies have been pouring in.
"It's nice to see we're going to have a good outcome here," Sullivan said. "These puppies have a chance."
Police want those with any information to give them a call.
