I Jiggle...First of all, love the dog!!! I have one just like your puppy....aren't they the sweetest?
About exercise, I discoverd the exercise ticker on this site (I am too new to have one yet tho) and that has really motivated me. I set my goal as 750 for July...since I just started my plan yesterday. I worked in my yard 30 minutes yesterday and then took my golden for a 20 minute walk and I am now down to 700 minutes for July. Just the thing to motivate me
Try it!! It was so wonderful not to try to walk a mile in a certain number of minutes..blah...blah.... I just did it, you know?
Hang in there.
