Well i am sad to say my three year old lab is over weight my wife has done it to all of us by over feeding so i had to take over feeding the dog this past month. I switched her food to the new purina active life, started giving her less, and i have been working her almost every day at least twice a day for the last month. She can't go for more than ten or fifteen minutes without her tounge dragging the ground and we have to stop before she gets over heated. The season starts here in three weeks and i need to get the weight off of her. Could someone suggest what kind of food i should get and maybe how much i should give her and maybe some other excersice routine. all opinions are welcome. Thank you.
