People are unaware of their behavior towards dogs sometimes. It's so sad to hear the poor little thing was struggling for his breath. I am all for exercising with or furballs. I find it more convenient when it comes to daily time management, and it's also a great bonding technique, but people should adjust to their dog's physical state. When I adopted Brando, my lab, he was quite overweight. I trained with him at took it day by day till he lost some weight. Now we run together. I put on my fav tights, and take hit chew toy with us every day...
Remember to love them and care for them - they only got us.
