Phoebe is a cross between a beagle and a Jack Russell terrier and we are extremely lucky to get all the best qualities from both sides. Her temperament is fantastic--always happy to see us, great around lots of people and other dogs, extremely affectionate, and quickly learning new commands all the time. We are not too sure on how big she will get as by looking at other Jackabee's, they all seem to vary so only time will tell. It simply adds to the excitement of owning her. She is an incredible dog and I highly recommend this breed to anyone.
