Hey Pet Parent,
You can check out our Ai-powered Pet Nutrition Planner to curate a diet plan for your pet that is tailored based on their age, weight, body condition and weight :)
If he doesn't like it, you can switch to some other form of protein like soya, paneer (only if he is found lactose tolerant), chicken, mutton or fish. As mentioned by team kuddle in the above message, you can go through nutritional planner in the Food section and give accordingly.
