This is how it is done!

Put the 2 pups in the enclosure this morning and it took about 1/2 a minute for Poppy to show me how she got out. The netting is on the inside of the old gate (on the left) , and she just climbed up it! Then sat at the top, not sure how she got down from there yesterday, but today I lifted her down, as I didn't fancy having to take her out to the Vets for a broken leg.
