we got our 7 year old lab over a year ago & the same thing she was quite over weight, she is also a low energy dog which i know is strange for a lab. i have spent over a year trying anything & everything & she always seem to loose a bit then put it back on, but lately fingers crosses she seems to be loosing weight. She is eating acana light & fit , the suggested feeding says she should be on 3 cups a day i started with that then every 2 weeks if there was no change in her food i would drop her feeding by 10% until i started to notice a change & we are now down to 1and a half cups a day which to me sounds every low for a big dog but as i said she is less active & because of her being a lab shes always looking for food so i add fruit & veggies to her food & she gets 2 spoons of organic pumpkin a day which is great for weight loss & it also makes them feel full http://www.nummytumtum.com/products.html
