Suresh,
Nice to hear things are going well for you. Keep up the good work!
One caution: dogs absolutely should NOT be given chocolate. You mentioned chocolate flavoring. Chocolate is toxic to dogs, along with other common foods like caffeine (coffee/tea), onions, grapes/raisins, macadamia nuts, walnuts, etc.
If you are going to feed homemade, which can be the very best for dogs, it is important to become familiar with poisonous ingredients for dogs, study/consult for proper diet balancing of nutrients, and use a quality multi-vitamin & mineral supplement (and if vegetarian/vegan, one specifically designed for vegetarian/vegan fed dogs).
