The dogs were allegedly taken from the Mount Vernon Animal Shelter on Tuesday and Wednesday of last week.
Two of the dogs were taken on Tuesday, and five were stolen on Wednesday.
The Friends of the Mount Vernon Animal Shelter have offered a $1,000 reward for information leading to the dogs.
They fear the dogs could be used for dog fighting.
Anyone with information about the dogs' whereabouts can call the volunteers at 914-841-1001 or email them at firstname.lastname@example.org.
