In reply to martinturner:
I take my two English pointers out with me wild camping in pretty much all seasons.
Pointers will go for hours, but when they stop, the do tend to get pretty cold so have to take something for them to sleep in/on.
Now for one night trips, where space isn't so much a premium in my sack, then I tend to carry this for them, however on longer multi day trips, where the need to carry food and bedding for them adds to much weight and bulk, then I make them carry it themselves!
They both have there own harness bags, panniers for dogs if you will, that they carry there own food, water and bedding and a small dog based first aid kit.
For the bedding one dog carries the base part of the sleeping system, and the other dog carries the top part.
Both parts I made myself. The base is a piece of silver foil insulation inside a pocket of waterproof fabric that I bought online. I sewed it in a pocket so that the outer can be taken off and washed separate from the insulation. I attached a couple of eyelets on the corners so I can peg this down.
The upper I made using the same method, except substituting the silver foil insulation for a piece of cut up down, 3 tog duvet. (This looked like I had murdered a flock of geese in my living room when in did this) again making a poctet out of waterproof material. It has the same eyelets on the corners, but also some elastic strips to run underneath the base of the matt to allow movement underneath.
Neither dogs were bothered by having to wear the bag harnesses, and only a couple of times have I had to free them up from a barbed wire fense after having got tangled up!
Edit: I use a tarp tent, not an actual tent if this makes any difference.
