Rex the runt

[Yami]

A little damsel strap to a mad scientists type scenario where Wendy the dog is lured by a charming but crazy singer whom wants to make her his chemical bride. Luckily Rex and Bob are there to rescue her at 7:29 http://www.youtube.com/watch?v=1XN4yes5Lww

Quite weird looking dog characters in that cartoon, some of them (like Rex) look like bears.
