I have a 4 yr. old Jack Russell female that I was given earlier this year. I don't know if she is spayed but she hasn't come into heat in the last 8 months. She is very sweet, loves to ride, and hunt squirrels. She weighs 10 lbs. and is only about 9 inches tall. I will give her to the right home where she will get more attention than I have time to give her. She loves all people, goats, cats, and other dogs.
