I walk my dog twice a day and only feed him when he is hungry. I try not to give him too many treats, but when I was trying to train him to play dead, he ate quite a few before I figured out how to use them.
Now he is plump and I don't want him to be that way - I would prefer to get him back to his ideal physique that he had before.
What do I need to do? I tried long walks and more exercise but it doesn't seem to help - do I just have to keep working at it? Or is there something else I am missing?
