Plenty of reasons not to walk them too Coops IMO

Ive got 12 dogs and can walk all of them at once on my walking machine.
So my option between walking machine or legs:

Legs: Can only handle 2 at a time
Walk for 1hr (im not a fast walker) which means id have to go out 6 times, which is 6hrs that can be better spent
Risk them walking on glass that i may not see, bindies or have other dogs come after them.

Walking Machine: Can walk 12 at a time
Speed set to go same distance as i would walk but in 30mins
At home so no stray animals, on a safe surface and whilst theyre walking i can spend that 30mins getting their kennels cleaned up, beds refreshed, clean up empty yards and get their breakfast ready all while watching them on the machine.

They dont seem to complain as its like a social event for them. They think its great. Kamikaze Spirit even has a talk all the way around to the others. Theyre speed is maintained, they arent sniffing and licking around the neighbourhood which this cant be helped sometimes as the buggers are strong.

No reason for me not to like a walking machine. Day before a race the go for a normal yet smaller walk out bush to get into their natural environment and spot some stir ups.
