I'm SOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO jealous! Ok, my dog is 4mths old tomorrow. He doesn't tell me when he needs to go out, he bites excessively, he's up at 5am (sleep in! What the heck is that?!?!?) He barks at me when I put him on a long lead outside in the yard. Can not obviously entertain himself for hrs!!! He won't let me brush him. He's afraid of the stinkin thing. What's up with that????? He jumps up at the kitchen table and counter tops and has gotten numerous cheese sandwiches from my youngest who fails to watch his food. Oh he at a whole pack of Trident gum that he jumped up at the kitchen table and grabbed off of it! I could go on and on too however, mine are not near as happy moments as yours! It's funny too cause Golden's and Labs are VERY smart and learn VERY quickly. That explains why your doggie is so smart. He has Lab in him. He does give me his paw(both actually one at a time when asked) and he does sit but that's pretty much it. When he's not obessively trying to find my underwear he's looking for a sock instead! Ughhhhhhh...Maybe at 5mth's I will be talking like you. Let's keep our fingers crossed!
BTW I just wanna squeeze your dog and hug him. He's the cutest thing. I'm so glad you didn't decide to give him away. He turned out so precious!!!
