Most any 4X4 you can get will be "Treated" lumber, most likely with a moisture content above 50% at best. Daved has a great Idea,, front to back on both sides is the answer!! A 4X4 will most certainly go Crazy with warping,twisting, checking issues when brought indoors. PM me the front to back deminsions,, the width of the legs,,I think I can match that stain color pretty close Jay. (Anything for a Puppy!!) Tim. P.S.,, Got your E-Mail,,Glad you like the 34 so much!! Shure is hard to put it down aint it!!LOL!! :p
