G,day Kit-e, i was just having a read of the canvas dog bed thread, and thought i should post. i had one made for my blue dog stubby when he was just a pup . i had it made so it sat across the back of the ute tub and was about 600 wide plenty of room for the bugger.3-4 years down the track the job changed slightly and stubby had to stay at home. i had stubby till he was roughly 15yrs old. the new hound if i can call him that, was brought a week after. well OI (as in oi get here) is now 12yrs old , every now and then i give the mattress a quick wash and its still going strong, OI will drag it out in the yard to catch a few rays it might get rained on , covered in crap does not matter a quick shake and its as good as new . i should have mentioned that the filling/stuffing is a piece of polyester insulation it was abouth 100mm thick and is now about 50mm thick so to cut a long story short , a good canvas bed for your pet will last quite a looooooong time cheers Graham( by the way thats OI on my avatar)
