(1) The monkey and dogs in "Hooch and Pooch" look a slight bit like Dr. Seuss' style. But the soldiers and backgrounds don't look like his at all, in comparing them to Geisel's comic strip work, and his children's books. I really doubt they were drawn by him.
(2) Dr. Seuss (Theodore Geisel), wrote and drew a comic strip for King Features during 1935, titled "Hejji".
And, If I remember correctly, he worked in animation with Warner Brothers during WWII, writing and storyboarding military training films, US propaganda films, the Private Snafu Films - (showing soldiers what not to do), and public service films on saving resources for The US War Effort. But, I don't remember seeing anything about his having worked in the comic book industry. I've never even heard of his "Hejji" strip being collected in book form.
(3) That looks like it might be Hal Sherman. I'm pretty sure I've seen that name in 1940s animation and comic book or comic strip credits.
(4) Ella the elephant doesn't look, to me, at all like Seuss' style. The monkeys look a slight bit like his, but the backgrounds don't look at all like his work.
(5) Superstitious Al-o-ysius' was drawn by Al Fago (I believe, through JCA (Jason Comic Art)
