Ohhh my. Mac is DEFINITELY in his terrible twos!!!! Started about 2 weeks ago (10 months) - it seems like he grew into a sassy little man overnight!!!! He's definitely more confident at the dog park, less respectful of Princess and he's ALWAYS into something. He is a jumping MANIAC at the dogpark - no longer seems to be able to sit nice when he meets people.

Still working hard on that one!!!!
He still loves to snuggle and be close with his mom, but he's gotten much pushier about it, and sometimes gets irritated with me! well...probably can't blame him....he has the BIGGEST jowals (sp?), so I pull them back to bear his teeth and say "rarrrrrr - vicious killer"...I think its hilarious - he used to sit nicely and let me do it, but now he doesn't think its nearly as fun anymore.
He's testing on commands - ie: pauses a few extra seconds before he sits and/or tries to walk away!!!
:rolleyes:
Princess went through this as well...the good thing is they DEFINITELY grow out of it!
here is an old - similar thread with others nutty terrible twos experiences....
