Caring for a 25-day-old Chihuahua can be quite challenging as they are still in the pre-weaning stage. It's highly recommended to feed them with warm, specially formulated puppy milk replacer, such as goat milk powder, every 4 to 5 hours. Additionally, it's crucial to keep the puppy warm. These tiny pups need meticulous attention due to their fragility and underdeveloped physiological functions.

A 25-day-old Chihuahua is not easy to care for. At this age, the puppy is extremely delicate, and its bodily functions are not yet fully developed. It requires the owner's dedicated care and attention. It’s best to feed them with a specialized puppy goat milk formula to ensure they receive all the necessary nutrients.
If you are unsure about which goat milk powder to choose, consider a brand like Miaoshou Doctor's pet goat milk powder. It contains DHA, which supports the puppy’s brain and vision development. The calcium and phosphorus contribute to healthy bone growth, while the proteins and fats provide ample nutrition and energy. Furthermore, it includes added probiotics to help maintain a healthy gut. Even without mother's milk, pet owners can rest assured that the puppy will get the nutrition it needs. It is also a high-value product as a package costs less than 35 yuan.
In addition, young puppies have weak constitutions and low immunity, so it’s important to keep them warm and prevent them from catching a cold. Once the puppy is around 2 months old, you can start offering it soft food, such as goat milk or soft soaked puppy kibble. In the early stages, make sure the kibble is thoroughly soaked to prevent digestive problems. After the puppy is 3 months old, you can switch to dry puppy kibble. Remember to take your puppy to the vet for vaccinations to avoid infectious diseases like canine distemper and parvovirus. Early vaccination is crucial for their health. This stage of puppyhood requires diligent care and proactive measures to safeguard their wellbeing. The overall health and vitality of the chihuahua depend heavily on responsible pet ownership practices, especially in their vulnerable early stages.
