Dog Armour can be created so many ways....Just some straps, tubes, empty water bottles, pieces of a kid's Halloween outfit and some gear charms...hot glue gun together, Voila!  A good place to start is a very basic gray or brown dog coat to attach everything to - that makes it easier to get on and off and more comfortable for your Steampup. Because when you travel interplanetary wormholes, you never really know what you'll find.

Puzzles

From Time machines to adventures of any kind, your Steam Pup will love a good puzzle and interaction with you.  Isn't that what Steampunk is?  Parallel universes and the mysteries of science.  Who knows, given enough time and treats, he might invent a flux capacitor and time travel.
