i have 2 jackrussels a old femal 16yrs old had her since she was a pup and i 1yr old that i got from a litter last nov i had 3 bread 2 had 7 pups got rid of all but these 2 one is hyper not spastic just loves to lick you in the face the other you have to put a stick of dynomite under her to get her up to eat. grew up with fox terriors and rat terriors love these dogs to death but if you want a loving dog thats just all around perfect for a pet get a small beagle. there just easy going and love affection
