My puppies start climbing by 6 weeks

I guess some lines of dog are more "ground-bound" than others ... and I suppose there are athletic/unathletic differences in what people are used to ... but no way would those pens hold pups of mine at even half the age of the dogs in there.

Anyway, don't want to digress too much off the privilege to see some of the dogs of long past, but did want to point out that many "old timers" really weren't all that knowledgeable in their care/practices at all.

A person's setup doesn't have to be super-expensive or fancy, but it should be able to prevent any possibility of escape.
