"Sparky is a Rat Terrier / Jack Russell shown here at 3 years old. Sparky's parents were registered purebreds. We got him when he was 6 months old. He has the JRT attitude and is the pack leader among the two of the dogs. (We have aCojack named Toby.) He is full grown and weighs about 11 pounds. Sparky is incredibility smart. Watching TV is his most favorite thing to do. On Sunday mornings he will wake us with kisses and then run to the end of the bed and look directly at the TV. Once we turn the TV on, he nestles himself into the covers and will watch TV all morning! Sparky is territorial and it took some time for him to adapt when we brought Toby home to him. Now that it's been a couple of years, him and Toby are soulmates and could never be separated."

"This picture is of our ever-curious, spunky Caszie, a Jack-Rat Terrier! In the picture, she is approximately 2 years old. She is the smartest dog and is also quite neurotic! She is the only dog I have ever seen that attacks vacuums, chases light beams, tries to "get" windshield wipers, and chases animals on hunting shows! She knows upwards of 15 tricks, all of which were learned before she was 9 months old! Truly an amazing dog. Fiercely loyal, she was my pick at first, but then she took over my husband. I can't even get near him, or she'll try to get between us or, if she can't, she'll sulk off to the corner and sit there, looking sullen. She just cracks me up!!"
