First of all, I find 2 Stupid Dogs to be much more visually enjoyable than Ren and Stimpy, funnier, and definitely cuter, but likeably, not annoyingly so. If one wants to succumb to making Ren and Stimpy comparisons, Cow and Chicken is a lot more similar (and is also better than Ren and Stimpy as well). The lunacy-prone personalities on that show have more in common with R&S than the 2 Stupid Dogs, who are much more easygoing, ordinary, and laid-back (except when they freak out). The scenarios are usually more innocent on 2 Stupid Dogs as well, and the humor isn't as crude. The visual style is also totally different from R&S, and looks very clean, simple, and stylish. The situations and adventures they get into are entertaining, but I'm not sure if many young children will understand some of the ironic references, like the darkly humorous name of a hair salon they visit printed on a wall sign in the background ("Curl Up and Dye").
Another thing about this show which I happen to love is the episodes featuring the updated Secret Squirrel, who used to have his own cartoons back in the 60's--you can look it up here on imdb.com. (As far as I know, reruns of those shows are also played on the Cartoon Network, but the new Secret Squirrel is a major improvement over the old one, in my opinion, and after watching a few episodes of the old one, I had no interest in watching any others.) Although I like the 2 Stupid Dogs a lot, Secret Squirrel is my favorite part. I think Morocco Mole is my favorite character--he wears a little fez and black round glasses, and he's adorably and hilariously slow-witted ("Do you remember where we first met, Morocco?" "Ummm... the gelatin store?"). The characters on the Secret Squirrel episodes are rich, numerous, and diverse, (characters they don't list in the credits for the show here are SS's female crimefighting friend whose name I don't remember, the assorted villians, and the chief may have a beautiful secretary as well, I'm not positive... but don't they usually?) and there seems to be more action and drama going on in them than on the regular 2 Stupid Dogs episodes. It's disappointing that they didn't develop it into its own series, because it would have been great.
I highly recommend this show. It's one of my favorites on the Cartoon Network, along with Cow and Chicken, and Dexter's Laboratory, the latter of which is in the same type of visual style as 2 Stupid Dogs. (Johnny Bravo and The Powerpuff Girls also share this style.)
