Jack is a playful, but energetic young Jack Russell/Chi Mix. We rescued him approximately four years ago from a couple in Stockton who had 3 Jacks and had got him after he was found dumped on CA Hwy 4, it was witnessed that he and 3 siblings were tossed out of a speeding vehicle. Jack was the Lone Survivor. We got him at a time when I was going through some eye surgeries and was stuck at home and need some company. He's a great companion and loves to take walks, rides in the car. He especially loves LONG Road trips. So if your a Ful-time RVer. This Guy is for you, he loves going camping, if you leave him off the lead he will run around about 4 campsites and comeback. So be forewarned. He loves to sit on your lap watching TV. It's not that we don't love Jack, it's that we have two other dogs and all three seem to be struggling for the same attention and I only have two hands. Plus, we have a new grandchild due in the household in a few months, so Jack's energetic mode isn't going to help too much with our daughter-in-law. Jack, when by himself is really good about following basic commands. He is also Crate and Dog Run trained. He will respond to most one word commands, but if extra words are added, it will confuse him. Thank you for considering Jack, if you have any questions, please don't hesitate to ask. all vaccines are current.
