Buffalo Police have two teenagers in custody in connection with the case involving a puppy that was set on fire in the city late last month.
Their names have not yet been released.
Because both suspects are in their late teens, police say they will be charged as adults.
A police spokesperson said a weekend tip from the public helped officers get to the suspects, who were picked up for questioning late Tuesday afternoon.
Phoenix is currently recovering at the Buffalo Small Animal Hospital. Officials at the Buffalo Animal Shelter say he will not be available for adoption until he is completely healed.
