How do you make a Teddy gain weight?

To fatten a Teddy, adjust diet and improve its condition. Give nutritious kibble on a fixed schedule to avoid hunger, and add protein-rich foods like boiled chicken breast, beef, egg, goat milk, milk cake, fish, nutrition paste and canned food.

Walk it daily; proper exercise improves fitness and appetite. Deworm regularly, and for gut problems feed easily absorbed food to improve nutrient uptake.
