I think Cruella did the job, despite her terrible giveaway name. I've never seen the movie but I gather they actually wiped out the lead female dalmatian (not in the gangster sense obviously) making it Pongo and Perdita instead. So maybe it was Pongo's original partner who most irked you. The bit I remember that annoyed me was when the dogs are trying to tell the stupid humans what county the puppies are in and nearly make themselves understood. I'm sure you remember. It definately would not have worked if Cruella had taken them to Lanarkshire.
