The American Animal Hospital Association says the microchip registry of Save This Life abruptly closed and their database is gone.
The coyote was "accidentally taken home by a (Massachusetts) family after they mistakenly identified him as a lost puppy."
Video of the scene shows the suspect forcing his way into the victim's home and leaving with the two dogs and the kennel they were housed in.
The breeder said one suspect charged toward her husband with an automatic weapon before stealing the pups.
A woman was scrolling through a list of adoptable dogs at her local humane society when she came across a photo that made her heart skip a beat.
The women asked to see a 14-week-old French bulldog named "Mario" before grabbing him and running out of the store, police said.
