Hello all. My family and I rescued a Yellow Lab today (it was a long process we met with multiple dogs to find a good match for our family). I am not a first time dog owner, but this is the first dog in about 5 years. The dog is a 4 year old female who obviously is undernourished, her ribs are showing and just looks skinny (not sure of her weight yet). The foster mom said she was only giving her 2 to 2 1/2 cups of food in the evening. My last Malinois was eating 6 cups a day and only weighed 72 pounds. My question is what brand of food and how much should I be feeding her, I have never owned a Lab. I know she needs more food and I am only going to increase it slowly. Thank you in advance.
