Bringing Home a New Puppy
The first months with a new puppy set the tone for the rest of their life, both in terms of health and behavior. At Warwick Animal Hospital, we walk Oklahoma City families through everything a puppy needs during that first year, from their earliest vaccines to the timing of spay or neuter surgery. Expect several visits during the first few months, and do not hold back on questions. There is a lot to cover, and we would rather you leave every visit feeling clear on what comes next.
Your Puppy’s First Year, Stage by Stage
Puppies grow and change quickly, and each stage brings its own priorities.
Birth to 8 Weeks: Early Development
During the first weeks of life, puppies rely entirely on their mother for nutrition, warmth and early immune protection through her milk. Most breeders or rescues will not send a puppy home before 8 weeks of age, since this period is critical for early development and initial socialization with littermates.
8 to 16 Weeks: Vaccines and Socialization
This is the busiest stretch of your puppy's early life. Vaccination boosters typically begin around 8 weeks and continue every 3 to 4 weeks until 16 weeks of age. It is also the most important window for socialization. Positive, low-pressure exposure to new people, sounds, surfaces and gentle interactions with other vaccinated dogs helps shape a confident, well-adjusted adult dog. Puppies who miss out on socialization during this window are more likely to develop fear or anxiety-based behavior issues later.
4 to 6 Months: Training and Growth
As your puppy approaches adolescence, house training and basic obedience should be well underway. This is also a common age range for discussing spay or neuter timing, especially since larger breeds may benefit from a slightly different timeline than smaller breeds.
6 to 12 Months: Adolescence
Many puppies test boundaries during this stage, and consistent training pays off here more than ever. Physically, most puppies are approaching adult size by the end of this period, though larger breeds may continue growing past their first birthday.
Vaccinations Your Puppy Needs
Puppies need a series of vaccines, since the immunity passed down from their mother fades gradually and leaves gaps that boosters need to close.
Core vaccines include:
- DHPP, which protects against distemper, hepatitis, parainfluenza and parvovirus
- Rabies, typically given around 12 to 16 weeks and required by law in most areas
Depending on your puppy's lifestyle, we may also recommend:
- Bordetella, especially if daycare, boarding or puppy classes are part of the plan
- Leptospirosis, for puppies with exposure to standing water or wildlife
Deworming and Parasite Prevention
Puppies are commonly born with intestinal parasites passed from their mother, even when the mother appears perfectly healthy. Because of this, we recommend deworming puppies multiple times during their first few months, along with a fecal exam to check for parasites that a dewormer alone might not fully address.
Heartworm Prevention Starts Early
Heartworm disease is spread through mosquito bites, and Oklahoma's long mosquito season makes year-round prevention essential. We recommend starting monthly heartworm prevention as early as your veterinarian advises, since treating an active infection later in life is far more involved than preventing one from the start.
Puppy-Proofing Your Home
Puppies explore the world with their mouths, which means common household items can become surprising hazards. Keep an eye out for:
- Electrical cords and small objects within chewing reach
- Toxic foods like chocolate, grapes and xylitol-containing products
- Household plants that are toxic if ingested
- Gaps in fencing or gates that a small puppy could squeeze through
A little prevention at home goes a long way toward avoiding an unplanned trip to the vet.
Spay and Neuter Timing
The right age for spay or neuter surgery depends on your puppy's breed and size. Smaller breeds are often ready between 5 and 6 months, while larger breeds may benefit from waiting closer to 12 to 18 months to support proper joint development. We will help you decide on the timing that makes the most sense for your specific puppy.
