When we got our Lab pup, Bailey, a year and a half ago, we decided to buy an outside dog kennel so that she didn't get into all of my plants. The idea was that we would leave her in there if we needed to run an errand. She's spent an entire 1/2 hour in it, when she broke my husbands wrist and I had to take him to the hospital. Our son came and got her out and brought her inside. So, it was a wasted $250. Or so I thought! I really wanted a greenhouse, and the kennel made the perfect frame for it!
My plants are still safe though. I fenced in all of the flower beds with rabbit fence! We just move the kennel/greenhouse into the veggie garden for the winter, and put it back out in the yard, uncovered, during the summer, just in case the puppy breaks a bone on someone else! Hopefully she will have calmed down enough next summer so that I can just uncover it and leave it in the veggie garden. I'll fill it with cucumber plants, and they'll have something to climb on!
