My son has several large breed dogs, and the only raw animal parts that are given to them would be bones. The local vet has agreed that cooked bones are more likely to choke a dog. Eating raw flesh is not recommended for our “wolf-cousins”. Truly, if they were on their own in the woods, they would survive by eating small wild animals. The house cat even enjoys an occasional mouse. You risk intestinal problems from germs or parasites found in raw meats. Love your dogs with well cooked meats, grains, and an assortment of vegetables. They really love what we eat! Good Luck!
No offense to you, but feeding your dog that is going to be 150 lbs,is a big mistake! dogs that taste blood crave it and one day you will see that a pet rabbit or a small child will fall victim to your pet, May I suggest Bill jack dog food most petstores have it and it is a great sourse of vitamins and minerals. Also extra vitamins are a plus but may put extra weight on your pet. good luck
