The Real Ghostbusters(1986-1991)

According to a Ghostbusters Wiki the Terror Dogs did make cameos in a couple of episodes, Egon's Ghost and The Copycat, and were apparently also just mentioned in one or two other episodes.

I actually revisited the Copycat episodes a couple of weeks ago. It's a better episode than I remember. The Terror Dog appears in an experimental dimensional portal that Egon is working on. RGB essentially implies that there are more terror dogs than just the two from the films.
The Scaring of the Green features a creature that isn't a terror dog, but is very based around them.

That was quite a clever little idea on their part, as it helps explain some of the discrepancies between the films and cartoon show, that were ultimately forced on the latter for various reasons. It was essentially how the TV show and film events were in the same canon (at the time, but not anymore, the show was officially retconned out of canon in 2009 when the game came out) but in a kind of soft-canon way. When it was original shown on TV here in the UK it had been edited for running length. I never knew that they actually went to the cinema to see the film at the end until I had the dvd box set.
Plays well with Citizen Ghost as a kind of movie-tie in double bill.

It wouldn't surprise me if the ending was removed in case it caused seizures - even by anime standards, that's some nasty strobing in the projection scene!
