New Puppy or Kitten Near Rosemead? First 30 Days at the Vet Explained
The first month with a new puppy or kitten is a lot. Sleep disruption, house training, puppy classes, figuring out what they'll actually eat — it adds up. But that first month is also the most important window for their health, and the vet visit that gets skipped or pushed back can create problems you won't see until weeks later.
If you're in Rosemead, South Pasadena Animal Hospital is about 8 minutes west on Garvey Avenue. Here's what to expect at those early visits, why the timing matters, and what should send you back in between scheduled appointments.
Why the first vet visit matters more than you might think
Puppies and kittens often look totally healthy when they come home from a breeder or shelter. That's usually true. But parasites don't look like anything — intestinal worms are common in very young animals regardless of where they came from, including reputable breeders. Heart murmurs, umbilical hernias, retained testicles — these are easier and cheaper to deal with when caught at 8 weeks than at 4 months. And vaccine timing is not a guess: the schedule depends on the animal's actual age and what vaccines they've already received, which requires a conversation with a vet, not a Google search.
The first visit is partly for your pet, partly for you. You should leave with a written schedule of what's due and when, a clear picture of the deworming status, and a list of signs that mean "call us today" versus "this can wait for the next appointment." That clarity matters when it's 9pm and you're not sure if what you're looking at is normal.
New puppy: what the first 30 days look like
Visit 1 — within the first week
This is a full physical exam plus a health history review. The vet goes over whatever records came with the puppy, assesses weight and body condition, listens to heart and lungs, checks for parasites or skin problems, and builds out the schedule for what's next. Fecal testing often makes sense here. The goal is to establish a baseline and catch anything that got missed before the puppy came home — and that happens more often than people expect.
Puppy vaccine schedule overview
Core puppy vaccines are the DHPP combination (distemper, hepatitis/adenovirus, parvovirus, parainfluenza) and rabies. The DHPP series starts at 6–8 weeks and repeats every 3–4 weeks until the puppy is at least 16 weeks old. That last point matters: maternal antibodies in a puppy's bloodstream can interfere with the immune response, which is why a vaccine given at 8 weeks doesn't fully "take" the way it would at 16. The series needs to go all the way through. Stopping early leaves a window of vulnerability.
Rabies is given once at or after 12 weeks, sometimes 16 weeks depending on the product. Bordetella (kennel cough) is recommended if your puppy will be around other dogs — daycare, boarding, training classes, dog parks. It's optional if your dog lives a primarily home-based life.
Deworming
Most puppies are started on deworming at 2 weeks and treated on a protocol through their early weeks. Your vet will confirm what's been given and prescribe additional rounds if needed. Roundworms and hookworms are the main ones — both are common even in puppies from clean, reputable sources. Roundworms specifically can pass from mother to puppy before birth and through nursing milk.
Spay/neuter timing
For most dogs: 4–6 months of age, before the first heat in females. Larger breeds sometimes benefit from waiting a bit longer to support full musculoskeletal development. Your vet will discuss what makes sense for your dog's specific size and breed — this isn't one-size-fits-all, and the right timing has become more nuanced in recent years.
New kitten: what the first 30 days look like
Visit 1 — within the first week
Same structure as a puppy visit: full physical exam, review of whatever records came with the kitten, fecal check if appropriate, and a vaccine schedule built from the kitten's actual age and history. Upper respiratory infections, ear mites, and intestinal parasites are very common in young kittens — even ones that looked healthy at pickup. All of these are treatable, and all are better addressed early.
Kitten vaccine schedule overview
Core kitten vaccines are FVRCP (feline viral rhinotracheitis, calicivirus, panleukopenia — essentially the cat equivalent of DHPP) and rabies. The FVRCP series works on the same 3–4 week interval logic as DHPP in puppies, continuing until at least 16 weeks for the same maternal antibody reasons. FeLV (feline leukemia) is recommended for any kitten with potential exposure to outdoor cats or cats with unknown vaccination status — and "potential exposure" includes future outdoor access, even if they're indoor now.
Spay/neuter timing for kittens
This is one that surprises people. Kittens can go into heat as early as 4 months old — earlier than most owners expect. Spaying before the first heat is recommended for females. Neutering at a similar age is standard for males. If your kitten came from a shelter or rescue, they may already be altered — this is common practice, especially in shelters. Check the paperwork.
Signs to call the vet before the next scheduled visit
In the first weeks at home, call us sooner if you notice:
- Not eating or drinking for more than 12–24 hours (shorter window for kittens under 8 weeks)
- Vomiting or diarrhea more than once, or any blood in stool or vomit
- Lethargy that's unusual — sleeping more than normal, not interested in play or interaction
- Sneezing or nasal discharge, especially if accompanied by eye discharge or loss of appetite
- Any labored breathing or open-mouth breathing (emergency — call immediately)
- Pale or white gums (emergency)
- Limping or reluctance to use a limb
Young animals can decline quickly. When in doubt, it's always better to call and ask than to wait and see.

Questions we hear often
When should I take my new puppy to the vet for the first time?
Within the first week of bringing them home, and no later than two weeks after. Early visits establish a health baseline, confirm deworming status, and build the vaccine schedule from the right starting point.
What vaccines does my puppy need and when?
Core vaccines are DHPP (combination) and rabies. The DHPP series starts at 6–8 weeks and is given every 3–4 weeks until the puppy is at least 16 weeks old. Rabies is given once at or after 12–16 weeks. Bordetella is recommended for puppies with dog-to-dog contact.
What vaccines does my kitten need?
Core vaccines are FVRCP (series starting at 6–8 weeks, continuing every 3–4 weeks through 16 weeks) and rabies. FeLV is recommended for kittens with any potential outdoor or multi-cat exposure.
When should I get my puppy or kitten spayed or neutered?
Generally 4–6 months for most cats and smaller dogs. Larger dog breeds may benefit from waiting slightly longer. Your vet will discuss the right timing at wellness visits based on your pet's size, breed, and individual development.
