This video of adorable Rory only provides more evidence that we could and should have a pony that lives in the house with us. Juannie has been fighting me on this for many years. A fully grown Rottweiler is as big as that precious pony and my cousin had two living with her in their 2-bedroom house. I had three ponies when I was a kid. I love them. Our yard is plenty big enough. So is our house. We could have one bedroom devoted to pony and pups.
