So since our first day of school, we've cut Palmer's food portion in half. He's still chubbs (as Johnny would say) but his poopie routine has drastically changed. He goes much less and not in a regular pattern as he did before. I think the weight loss and bathroom habits will stabilize eventually, so we're trying to stick to the plan. And in case you were wondering, yes, we still give Palmer treats (doggie treats, some peanut butter, etc.) but as us human-folk are taught... all in moderation.
In addition to downsizing his meals, we've divvied up his food ration to create multiple 'training opportunities' throughout the day. Instead of one or two daily meals, Palmer gets 15 to 20 smaller portions of food. Each portion is used as his reward for sitting when given the hand signal. As our instructor pointed out, in one week, Palmer would have 'sat' anywhere from 105 to 140 times successfully. Great pointer for you doggie parents out there!
Anyway, I think that's enough of an update for now since I am anxiously anticipating our 2nd class tonight. Here is a picture of Palmer planting a big wet one on Auntie Rachel, Auntie Janet and me (thanks to Auntie Genee for taking the great pics!):
