Dalmatians are traditionally associated with firefighters. But not once have I ever seen a dalmatian on 9-1-1, you would think Bobby or one of his crew would own one for the station. Maybe they were on season 1 and I missed it, didn't start watching until season 2. There might be some breeds of dogs that can't be trained for acting. But we know from 101 Dalmatians (the live action version with Glenn Close and Jeff Daniels) that they can be trained. And whatever restrictions that humans have had to follow in the last year wouldn't apply to animals.
