Actually Zebra has had 3 obedience classes. One basic puppy class when he was 2 1/2 months old, the second one was a clicker class and the most resent was an adult dog obedience class, which he just graduated from last weekend. But like I said he never is that way with me untill today. I suspect he was testing me to see if I was alpha. He know all his basic comands, sit, down, stay, wait, leave it, roll over, crawl ect. The only problem is that I think that I'm the only one he thinks is alpha. whenever he growls at my mom, dad, bro they just say 'no' and walk away. and when I try to explain that you can't let him do that they basically ignore me, but then again what do I expect from a younger teenage brother, my mom and dad. :roll: I probabaly made it seem that he is always does that be he dosn't. He has actually gotten much better. when we first got him he had bit my mom realy bad when she tried to take something away from him. Now it's not so difficult so he has come a long way from his bad behaviors (and trust me he had allot!). But in the beggining even our trainer noticed that he was trying to be alpha dog with eveyone including her. *sigh* of course I have to pick the most stubborn dog out of the bunch. But all in all he is good. I just thought it was funny because he protects the potatoes and not anything else around the house. Such a strange dog. :)
