[Lovely G] Connection with the Simpsons? YES, but not an important connection, IMHO.

[Software] Greyfriar's Bobby? NO
[Dujon] First appearance in print? YES
[GL] First appearance on TV? NO (see above)

[Ye Olde Softeware] Lassie? NO

[Dujon] In a children's story? NO

Ooops, not sure what happened there, but I thought I'd add a summary, just to help out, as I thought this would be simple. Not that there's much to summarize.
This is a fictional dog; created by a man; has appeared in multiple media (from the list: book, film, tv, radio, Grand Opera), but first appeared in print; has a slight link to The Simpsons (which is unlikely to be useful).
The AOTC was not created by A.A.Milne; is not a Disney character; is neither Greyfriars Bobby nor Lassie; was not introduced in a children's story.

[GL] HotB? NO

[Chalky] Toto? NONO

[Dujon] A Homeric character? NO

An assumption appears to have been made.

[Chalky] A cartoon dog? YES *Much applause*
[Ibid.] Scooby Doo? NO *oohs, aahs and groans of disappointment*

and the Red Baron

[Software] Snoopy? YES!
My childhood hero. I still drink out of a Snoopy mug at work, which even has a Snoopy stand to sit on. Such is my fondness for the special beagle, that when I tried this AVMA on family members, and as soon as I said "fictional dog", they guessed it. The assumption, of course, was that "print" referred to books. Also, The Simpsons makes several nods in the direction of Peanuts and Snoopy - e.g. "Hungry, Hungry Homer" which was on C4 last week finds Homer asleep on top of the kennel, and Bart says "Good grief!" more here.
Here, Software, take this flying helmet, goggles and scarf set - may it serve you well!

Can I think of something that won't cause as much trouble as last time?

Let's try this, then:

MINERAL with ANIMAL and Vegetable connections.

Sorry Software - too complicated - only kidding.
But whilst we're about it, PLEASE answer the questions in a straightforward manner ... takes bloody ages to work out what you're trying to reply to usually! ;-)

Sorry, sorry, sorry ...
