Oreo Cat answered question 7/13/2011 Should i get another dog to keep my Jack Russell less lonely. During school time, he is left alone for 6 and 1/2 hours a day and his toys are becoming boring for him. If so, what breed? I think you definitely should get him a friend! Possibly a dog close to his size, maybe even another jack russel, or a pug, or any kind of terrier. :D
