Oliver is a 2 y/o Boston JRT. When we got him, we were told he was Boston/Toy Fox. At our first vet visit, my vet, who breeds JRTs, swore he was one. After doing some research on the breed and consulting others, It has been decide that he definitely is a Boston/JRT. I have the best of both breeds in him! He's loveable and loves to snuggle, plus he has enough energy to keep me busy. A smart little bugger too! Would definitely consider getting another one!
