"Who let the dogs out?!" - Pavlov getting angry

Pavlov is sitting at a pub enjoying a pint; the phone rings,and he jumps up shouting: ""Oh Shit, I forgot to feed the dog!""

When Pavlov was done with his experiments what did he do with his dogs? Donate them to the salivation army ^^I'llseemyselfout

I'm not exactly sure who Pavlov is... But the name does ring a bell.
