Hey Susie, on the subject of fencing, back when I was engaged, and had my first greyhound and my retriever mix, we went to Tractor Supply (don't know what you have in your area) and bought a roll of what is considered horse fencing. It's flexible, yet sturdy, I think 1" x 3", bought t-posts and wire brackets. Did a big back yard for around $100 and still had fencing left over.
The fiance is long gone now, and precious Bart (formerly Bet-On-Bart) left this earth many years ago, but my love of greyhounds still remains and so does the fencing!
My old man Randy is 12 1/2 now and the love of my life. Give your needle-nose boy hugs from me, okay?!
