hi 'shrimp and welcome.......
dog show folks and handlers often use 'portable exercise pens' in a variety of sizes...based on dog height...i've got a zinc coated product like this...

that i've had for nearly 20 years...folds very compactly...6 panels or add more.
it's about the gauge of 'grill/grate' so it's study without overkill.
works great on grass or tarmac....
just google 'exercise pens dogs portable'...many vendors...
be forwarned however that many rv parks and camping parks expressly forbid using outdoor pens, like these...some parks are fine with 'em.
there are also some nifty folding dog houses...but again many places don't allow them...
it seems more parks allow 'stakes with a line, than portable runs...
happy camping the nwest offers great options...
cheers
