Cindy Lou is, by far, the best dog we have ever had! She is a ball of energy that never runs out. She is some sort of Jack Russell Terrier mix, but we're not sure what. She had other owners, but they dropped her off at the vet clinic and one of the assistants contacted us to see if we wanted her--and we did. She's a great dog, but the second she gets into trouble, she puts on a sad face and begs. She's very stubborn, but we love her to pieces!
