Preferably NOT something smaller than the Jack Russell! JRTs (Jack Russell Terriers) are quite competitive, as I'm sure you know, and have rather a short temper on the whole. A small breed dog would be at a disadvantage in a fight with the bigger dog. Therefore, it would seem that another terrier breed around the same size would be the best choice. I personally have a shepherd/husky cross & 2 JRTs......the larger dog is undisputed alpha dog, but the two smaller ones are constantly wrangling for dominance.
According to the Jack Russell Terrier Club of America breed standard, a true Jack Russell is between 10 and 15 inches high at the withers (top of the shoulder blades). However, there are a lot of JRTs or mix breeds that don't quite conform to this standard. Generally, you won't get one over 15 inches at the withers - that would be a Parson Russell, which is slightly different. Source: See related links
