This is amazingly smooth and very well done The only thing I noticed was that in real life when big cats walk their front paws tend to turn inward a bit before they put their down. I can see a bit of that in the background front paw of your animation but not so much the foreground one. Just a bit of opinion x3 don't mind me. Otherwise though it really is flawless and very very smooth :3 Very nice job, mate.
Thank you! umm... by sausage dog, you mean a dachshund, right? well, it would be just like any other four legged walk cycle, except for timing & spacing. The basic concept is using the bipedal walk cycle again but in reverse order for the second pair (hind legs). Same would be true for insects with six legged walks (meaning, the third pair would mimic the first pair of legs) or say spider where the last pair would mimic the second pair & so on...
Maybe you would like to download a book (*free registration) that has helped me immensely in understanding the concepts... Animator's Survival Kit (pg. 330, in your case) 35 Mb -> [link] a few videos that might explain it better visually -> [link]
When I first started animating traditionally 5 years ago, ALL my animations were awful! but sure was fun scribbling away on those flip-books! Never worry about that... It will only get better over time & practice, never worse. As long as you understand the '12 basic principles of animation' you're golden!
If you have ANY doubts or queries, feel free to ask away! Cheers!
Thanks for detailed comment! I took a look at the videos, but I can't download the book What are the 12 basic principles of animation?
The relation of the different legs in a fluent movement is really interesting, but I think it is really hard to coordinate Do you often use certain constants (like one part of the body, that doesn't really move) to orientade? Or can you do it just like this?
Thanks again for the helpful tips and your encouraging!
Oh and yeah, I mean a dachshund, didn't know that it is called the same in English
You're always welcome! oh okay. My apologies. I could have explained it a bit better, I guess. That download requires that you register @ 4shared.com first.

The 12 principles of animation are just basic guidelines/principles first introduced by Disney animators back in '80s. It's helpful, to say the very least, and most animators still use them quite lovingly as it makes the work easy. There is no hard and fast rule that you simply must use them all for animating, of course... but it does cover most of the areas an animator/audience might find functional. To know more about it, check out wikipedia's entry on it, okay? -> [link]
I'm glad you notice the relational pattern between different legs... Observation is the key! Once we break down every 'pose' & understand the repetition & mirroring effects (for lack of better words), it won't be hard to coordinate. Here have a look at this image -> [link] You don't need to keep one part of the body stiff/constant, per sť. Although, when you think about it, the first frame is stiff-as-a-2d-drawing can be! . It's only by 2nd frame do we see the illusion of movement, do we not? My approach is quite close to 'pose-to-pose' where all the pivotal points move in all desired frames/drawings. By pivotal points, I mean 'joints' of the moving bones (even muscles/hair/other appendages like antennae & so on, for secondary animation, if required). Place dots(one-dimensional) where all the joints are located. Simplify the forms to shapes and simply the shapes to lines/curves. Once the simplified stick-figure works, you can animate using shapes/silhouettes (two-dimensional). Last thing is just cleanup, mostly... to further animate it using forms(three-dimensional), meaning it has to look "believable" depending on the effect you're going for. At this point, think of it as bones & muscles sticking & sliding underneath the skin, as far as appearance is concerned. The rest... is really up to you & your unique style!
You remember how I mentioned about second pair of legs moving in alternate fashion to the first pair? Well, it's not ALWAYS so. Same goes for guidelines/principles etc... But you got to know the rules, before you tweak them!
