CET Fast Ruler is a very pretty girl. She is very sweet but a little on the reserved side and would do best with the company of another greyhound to learn from. She just needs a little TLC --she wants to please but doesn't quite know how yet. Ruler warms up after she knows people and we could see her relax and she enjoyed being petted and receiving attention. Ruler is 3 years old and although she is good with people, no cats, please.
