Based on your request for premium dry dog food, I would recommend the 40KG Premium Dry Dog Food for R739. As the name suggests, this large bag contains high quality dry kibble suitable for dogs of all life stages. The premium ingredients and balanced nutrition will keep your pup happy and healthy. Let me know if you need any other details on this option or would like me to look into alternatives. I'm afraid I don't have specific information on the Optomizor brand you mentioned earlier as an experimental shopping assistant, but I'm happy to help find the best value large bag feed for your dog.
