DH,
Let me see if I can help you out. I have had the same problem with my dogs. They never stay the same weight LOL. now if you are looking for a great weight gainer, go to the store and get a few things. This mixture works great. Just do not feed it to them everyday because it will make them fat as a hog LOL. But it will put weight on him fast, Im talking a few days you will see a difference. This is what you need.
10 lbs of cheap hamburger meat
1 lg box Total (tm) cereal1
1 lg box uncooked oatmeal
15 oz jar of wheat germ
10 eggs
10 small pkgs knox unflavored geletin2
1 1/4 cup vegetable oil
1 1/4 cup unflavored molasses
pinch of salt
Pedialyte to drink
1. Mix all ingredients together in large (or larger) bowl.
2. Place in freezer bags, appox 1 lb per bag.
3. Place in freezer, thaw as needed.
4. Feed raw. Just pinch off the amount you want to feed and
roll into a ball. Place on top of regular food.
This recipe is good for putting weight on a dog. Be careful though, it will put weight on the dog in a matter of a few days. A lot of weight in a matter of a few weeks!
Hope this helps
Tim
