The pics of Blaze are older, I haven't taken new ones of him lately.....I do so today.
However, he has lost weight. We decided as a family we were encouraging him to overeat. We'd feed him whenever he wanted, and we'd brush or pet him while he ate, so whenever he wanted attention, he'd go to the food bowl.
He's now on a schedule for food, and a set amout of food to be given. When he's eating, we ignore him. We also try to make him more active, making time to play with him, make him chase balls and toys on strings.
Loved the series you posted with the underwater dogs! The shots are amazing!
