NORFOLK (CBS) – Police suspect a “backyard breeder” may be responsible for abandoning several dogs in Norfolk and other towns in the surrounding area over recent weeks.

Norfolk police and the town’s Animal Control Officer are investigating after two dogs were found in the area of the Pond Street Recreation Complex on March 3.

The first dog was a male King Charles Cavalier that appeared to be about five years old. The dog suffered extensive injuries before it was found, and it was later euthanized.

A second dog was found later the same morning in the woods nearby. Police said the dog is a black cocker spaniel that is about three or four years old.

While investigating, police found that a female cocker spaniel was recently abandoned in Milford.

In addition, two more cocker spaniels were found dead on the side of a road in Millis on Wednesday.

Norfolk Animal Control is offering a $1,000 reward for information that leads to the arrest of the person who abandoned the animals.

“The investigation has led us to believe that these animals were used for breeding locally and placed for sale to the public at one point. We are interested in hearing from anyone with any information on those who may be breeding Cocker Spaniels, King Charles Cavaliers and Cockaliers,” police said.

Anyone with information is asked to call the Norfolk Police Department at (508) 528-3206.
