Care for a Chihuahua puppy starts with frequent, puppy-appropriate meals, an early veterinary checkup, gentle training and careful protection from cold, falls and rough play. Because tiny puppies can be vulnerable to low blood sugar, ask your veterinarian to tailor meals and preventive care to your puppy’s age, weight, health and vaccine history.
What should I feed my Chihuahua puppy?
Choose a complete food formulated for puppies. Food suited to a dog’s life stage is intended to supply the nutrients it needs; ask your veterinarian to review the food, portions and your puppy’s body condition. Keep fresh water available. Avoid relying on treats or table scraps, which can add excess calories; cooked bones and high-fat foods are also poor choices. The American Kennel Club’s Chihuahua guidance and VCA’s breed guide offer additional breed-specific context.

How often should a Chihuahua puppy eat?
Very small puppies may be prone to hypoglycemia, or low blood sugar, and VCA advises feeding Chihuahua puppies often. There is no single portion size or interval that fits every puppy: age, weight, health, activity and the food’s calorie content all matter. Ask your veterinarian to set a routine and explain how to adjust it as your puppy grows.
Low energy or listlessness can be warning signs of low blood sugar. An older Chihuahua Club of America handout also identifies long gaps between meals, chilling and stress as possible contributors. If you suspect hypoglycemia, contact a veterinarian urgently; do not rely on home treatment in place of veterinary care.

When should my Chihuahua puppy see a veterinarian?
Arrange an early examination and bring the medical records provided by the breeder or rescue, including vaccination and deworming history. The first visit may include weighing your puppy, a physical examination, a stool check for worms and discussion of feeding, parasite prevention, microchipping and spay or neuter timing. The AKC’s first-visit guide describes what to expect.
Plan follow-up visits and preventive care with the veterinarian. Vaccines and timing depend on your puppy’s history and local disease risks, so use a veterinarian-directed schedule rather than applying a generic timetable. The AKC vaccination guide provides general context, not an individual plan.

Signs that warrant a call
Contact a veterinarian about persistent or repeated vomiting or diarrhea, particularly if both occur together; loss of appetite; unusual thirst; eye discharge; trouble urinating; or sudden irritability that could indicate pain. For a very small puppy, do not wait to seek advice if it is unusually weak or listless.

Begin calm, positive socialization early. The first three months are an important period for introducing a puppy to different people, sounds, surfaces, handling and environments. Keep exposures gradual and positive, and let your puppy retreat or take a break if overwhelmed. The AKC socialization guide, updated August 11, 2026, outlines ways to approach introductions.

Socialization does not mean taking an incompletely vaccinated puppy everywhere or letting it meet every dog. Ask your veterinarian which outings, puppy classes and dog contacts are appropriate given vaccination progress and local infectious-disease risk. Avoid unfamiliar dogs and public settings your veterinarian considers unsafe.
Use rewards and consistent house rules
Chihuahuas can learn quickly. Use gentle, reward-based training rather than force, and make household expectations consistent from the start. For house-training, offer regular opportunities to go outside, reward the behavior you want and stay patient; avoid punishment that can make the process more stressful.

What grooming does a Chihuahua puppy need?
Both coat varieties need regular nail and dental care. Brush your puppy’s teeth regularly with dog-appropriate supplies, check its ears and keep nails at a comfortable length. VCA notes that Chihuahuas can be prone to periodontal problems, making dental care worth starting early.
| Coat variety | Brushing guidance |
|---|---|
| Smooth coat | Occasional or weekly brushing is generally enough. |
| Long coat | Brush two to three times a week to help prevent tangles and mats. |
These coat-specific recommendations are described in VCA’s Chihuahua guide. Check your puppy’s coat as it grows and brush gently so grooming becomes a familiar, positive routine.
