putting weght on a dog

I just went through the same thing. She still acted normal, but the pups were really bringing her down. For three weeks, I fed 6 cups of the Diamond puppy (I suppose most puppy foods would do the same). Anyway, 6 cups of puppy food, add two raw eggs, one can of soft puppy food and fill the bowl 1/4 full of hot water and mix it all together. I keep mixing the contents until the hard puppy food started to absorb the egg and water and get semi soft. She would inhale those 6 cups and then I would give her free choice hard puppy food. At three weeks I had to really cut it down because she had gone from bones to obese. I worked for a Vet for years and we used this formula quite often. You can also use powdered calf milk replacer to the mix and speed things up even more. Good luck to you.
