I'm currently trying to start a 4week 2day old puppy on raw diet, I have been using Leerburgs puppy formula, I am just starting to add hamburger to it, Can someone give me a idea on how much hamburger to start adding in. Thanks!

Hii, Debbie. About the amount of hamburger I unfortunately can not tell you anything. I changed to raw food diet following the LB book "Raw Dog Food" from Carina Beth MacDonald.

I started with chicken breast and nothing else for a week. Could also have started with some other meat. It is good to change only one thing at a time, in order to see how the dog reacts. Then try out the next, for example heart or some other muscle meet. organ meet, meety bones (never cooked, always raw, and for puppies of course smaller ones depends also on breed and age) I could soon feed my dogs with all kinds of meets. Now I give sometimes just one type, other times a mixture. I also add about 2-3 times a week a raw egg (important not only the white, the yolk too).

You can also prepare a glop with a mixer, put the whole egg with the shell in it, perhaps together with a yoghurt and one or two leafy veggies, zucchinis, limp carrots, tomatoes, garlic and other vegetables (never onions!, poisonous for dogs). also fruits like bananas, apples. But of course not all together. Keep it very simple at first.
Once the dog is used to more different meats etc. it is important to feed a wide variety.

The amount: Carina advices to feed 2-3 percent of the expected adult weight daily. Or between 5-10% of the puppies current weight. This depends on the individual puppy. Not all dogs have the same metabolism. Some gain more weight than others. So you'll have to observe this. You probably know about the rib test, a very good measure to see if the dog has ideal weight.

Hope that helps a bit. I have made very good experience with raw food with all my 4 dogs.
