JJ is one happy dog which makes us think the letter Js in his name must stand for Joyful and Jolly! JJ is full of life and is estimated to be 2.5 years old and weighs just under 12 lbs. If you love the energy of a terrier you will love JJ. He has been in foster for a few months and has loved getting to play with other dogs He has done well in a scheduled environment which has helped his potty training. JJ loves treats. Using his love for treats has really helped him with working on basic commands. JJ would love to travel to Wisconsin mid-November.
