It's hard to tell without knowing the situation, but some dogs will tend to nip and bite as part of play or making a correction of our behavior, which both are no good. Be consistent with corrections, never laugh or tease the dog or prompt it to do it again. As the person before me said, stand up straight, cross your arms or put them on your hips and give him a firm "NO!" If he keeps doing the bad behavior, find a good trainer to help you break his bad habits. As far as not coming inside when called, the Spaniel in the breed has a great hunting instinct, so that would prove a challenge. One way to do the "come" command, break a treat into pieces (2 or 3 is fine) and say very cheerfully/excited "COME!" and when he does, give him the handful of treats, this is called a "Jackpot!" Overall, definitely get help from a trainer because he's almost old enough to start. Have fun!
