The First Year of Puppy Care: A Practical Timeline

Homecoming to About 12 Weeks

• Complete the new-puppy examination and review all wellness, vaccination, and deworming records.
• Continue the veterinarian-directed core vaccine series and discuss lifestyle vaccines.
• Discuss fecal testing, intestinal parasite treatment, and flea, tick, and heartworm prevention.
• Keep food consistent while growth, stool, appetite, and body condition are monitored.
• Begin safe socialization: different people, surfaces, sounds, handling, grooming tools, and controlled experiences without exposing an incompletely vaccinated puppy to avoidable disease risk.
• Start name response, potty routine, crate comfort, gentle handling, and bite-inhibition work.

About 12–16 Weeks

• Continue vaccine doses at the intervals chosen by your veterinarian; AAHA guidance places the puppy core combination series between 6 and 16 weeks, typically 2–4 weeks apart.
• Receive rabies vaccination according to law and veterinary guidance.
• Continue parasite prevention and repeat fecal testing when advised.
• Enroll in a well-run, positive-reinforcement puppy class when your veterinarian agrees it is safe.
• Practice brief alone time, calm greetings, leash skills, recall, and cooperative grooming.

Four to Six Months

• Teething intensifies; provide safe chews and protect household items.
• Monitor retained baby teeth, bite alignment, and oral development—especially in toy breeds.
• Maintain regular professional grooming and home brushing. Handle feet, ears, mouth, and beard or facial hair gently and often.
• Revisit meal frequency and calorie needs as growth changes; do not chase a target weight without veterinary advice.
• Discuss spay/neuter timing based on the individual dog, breed, health, contract, and veterinarian’s advice.

Six to Nine Months

Adolescence can look like forgotten training. Reinforce the basics without increasing punishment. Continue controlled social experiences, reward calm choices, prevent rehearsing nuisance barking or chasing, and provide age-appropriate mental and physical activity.

Schedule follow-up veterinary care when vaccines, parasite tests, medications, growth, teeth, or reproductive planning require it.

Nine to Twelve Months

• Review body condition, adult food transition, dental care, exercise, and preventive medications.
• Confirm microchip registration and update contact details.
• Plan the first annual/young-adult preventive visit and future vaccine schedule.
• Continue training beyond puppy class: reliable recall, polite leash walking, handling, settling, and household manners.
• Keep grooming appointments consistent; matting, nails, ears, and dental disease do not pause when the puppy coat changes.
