Bernstein said they try to find rambunctious, energetic puppies to enter in the bowl though even if a dog falls asleep on its way to the end zone, it can be funny. Puppies chosen for the show have to be between 10 and 15 weeks old, healthy and sturdy enough to be on the field with playmates. All breeds are considered because ‘‘we try to reflect what’s out there in the adoption world. A lot of those breeds are mixed,’’ Toporoff said.
Producers also were trying to find ways to incorporate older animals into the show, since shelters have more trouble finding homes for them than they do puppies and kittens, Toporoff said.
As with all reality TV shows, the behind-the-scenes casting can lead to problems. Viewers often come in seeking a dog just like one on the show, and ‘‘then the lawyer brain kicks in, and you have to make sure you let everybody know not every dog plays football,’’ said Bernstein, who is also an attorney. ‘‘People will adopt the kind of dog they see in the movie and they'll expect their Dalmatian to know how to use a word processor and not understand that was a cartoon.’’
‘‘Some dogs like to play more than others. But don’t come in thinking every Chihuahua can play football,’’ she said.
The ‘‘Puppy Bowl’’ airs on Feb. 3 from 3 p.m. to 5 p.m. in all time zones and will keep repeating until 3 a.m. The Super Bowl starts at 6:30 p.m. ET and 3:30 p.m. PT.
