Here he is at Eighteen weeks and a hefty 43 pounds!! As you can tell he was much easier to hold back when he was 10 pounds. He continues his obedience training and is doing very well. He still likes to act agressive towards cars but has really calmed his act down as he is learning a stretched neck is not worth it. Gus still has plenty of puppy left in him and continues to socialize in many areas. He is almost through his teething process which seemed to give him more problems than any other dog I have owned.
