Puppy puberty.... phew

Funny, my beautiful, sweet, easy going little puppy has disappeared...... instead has arrived a long legged monster, suffering from attention deficiency and hyper activity. She is testing her limits continously: for how long can I bark at Yankee before he gets annoyed? how much can I bite Sammy before she beats me up? will mummy REALLY scold me if I chew this? or that? or perhaps this?
sigh..... I KNOW ... it is a passing phase... necessary for any youngster to find her place in the pack, learn to behave, etc, etc..... but, I do think we all look very much forward to it being over again.
