i have 2, and they do root a bit
more so when little, as they get older, they do it less and less, but they do do it
it isnt anything like other breeds though, and they dont plough it all up, ive had mine on my garden bit and merely stepped in any clods, they certainly didnt ruin the surface but it would depend on land size and length of time i would imagine
ive also found that they only do it when really hungry, otherwise a full belly = sleepy time
