I believe that Dog Trouble used the red spotlighted "An MGM Cartoon" card, like Puss 'n' Toots and The Bowling Alley Cat.
It's hard to say what style
Dog Trouble had. It may just as well have had the blue titles. If someone could access the original copyright synopsis, which, if it's like the synopses for later cartoons, would describe the textual content of each card, then that may reveal the answer. Thad Komorowski and David Gerstein looked at copyright synopses for MGM cartoons (including this one) several years back, so one of them may or may not know.
If Wild Honey had "Runnin' Wild" music and has credits, I believe that Sufferin' Cats also did that, wheras other cartoons with the music (Dumb-Hounded, Red Hot Riding Hood and The Lonesome Mouse) had no credits.
According to Thad's
MGM Cartoon Filmography by Production Number, the original version of
Sufferin' Cats did not have animation/music credits. This makes it an interesting exception among the MGM reissues; other reissues of cartoons without animation/music credits did not have them added.
Well, I believe that style lasted until 1943, as evidence showed that it was used as late as The Lonesome Mouse. A real mystery is that title card where Tom is holding a derby wile Jerry is in a high-chair.
You know what's weird that I just found. The current print of The Bear That Couldn't Sleep came from a late 1950s reissue (with blue open-matted lion logo), but the opening credits themselves (Barney Bear headshot and "A Rudolf Ising Production" card) came from the 1953 reissue, as the look of the credits have an Academy ratio design.
Cole Johnson posted in the comments on Gerstein's initial
blog post showing original
Tom and Jerry titles several years back that he's seen that same image with Jerry in a high chair used in MGM promotional material/ads of the 1940s. Note that the original pencil drawing of this image has the "Tom and Jerry" text at the bottom crossed out. Perhaps they initially intended to use it as a title card but changed their minds and it ended up being used for promotional uses instead. Unless it was used for
The Yankee Doodle Mouse (who knows?).
Baby Puss most likely used the title card that
The Zoot Cat and cartoons that followed used, since it was the first cartoon to use the
Tom and Jerry closing titles, which match in style.
The blue lion logo on
The Bear that Couldn't Sleep is from the 1953 reissue.
