* Formula: Continue to offer formula every 2-3 hours, or as often as your puppy indicates they are hungry.
* Other foods: You can start to introduce other foods, such as soaked puppy food, around week 4-5. Start by offering a small amount of food, such as 1/4 teaspoon, mixed with formula or water. Gradually increase the amount of food and decrease the amount of formula or water over time.
Here are some specific foods that you can offer your four week old chihuahua:
* Soaked puppy food: This can be made by combining puppy food with water or formula and letting it sit for a few minutes until the food is soft.
* Baby food: You can offer your puppy pureed baby food, such as chicken, beef, or vegetables. Make sure to avoid baby foods that contain onions, garlic, or other harmful ingredients.
* Cooked meats: You can offer your puppy cooked meats, such as chicken, beef, or fish. Make sure the meat is cooked thoroughly and boneless.
* Vegetables: You can offer your puppy cooked vegetables, such as carrots, peas, or green beans. Make sure the vegetables are cooked soft and mashed.
* Fruits: You can offer your puppy small pieces of fruit, such as apples, bananas, or strawberries. Make sure the fruits are ripe and free of seeds.
It is important to introduce new foods slowly to avoid stomach upset. If your puppy has any negative reaction to a new food, such as vomiting or diarrhea, stop feeding it and talk to your veterinarian.
