Well it's hard to get a good idea of his size and build from those photos but my initial reaction is that there is Jack Russell in him.
What is his personality like? Is he tenacious/stubborn/independent? Is he smart? Does he have a strong prey drive? Energy level? Preferred style of play?
Often it's easier to determine breed background by behavioral characteristics rather then just physical looks.
ETA: The other breed that I see is some sort of pointer.
