I have been following your posts as we got our precious goldens around the same time. As everyone has said, I am sure you and Mercy will pass as time goes on. I had such high expectations of Ryder and I when we first started our training but as he has gotten older I realize I need to let him also be the puppy that he is. He is so smart and attentive and does great with training but given the choice of working with me or going to see a dog, the dog wins out. I think it's great though that our goldens are such loving creatures and want to play all the time!!! I'm sure as they mature it will come, I feel the training certainly goes in phases.
We have been off for a few months after taking puppy K and basic obedience at our local Petsmart. I've finally found a trainer at a training facility to work with and am excited to start up again. That's been the hardest, finding a class that works into my work/kids schedule. Keep up the good work, our pups still are young!!!
