Key Takeaways
- Schedule a veterinary wellness exam within the first week of bringing your pet home.
- Core vaccinations protect against the most common and serious infectious diseases.
- Life-stage appropriate nutrition — puppy, adult, senior — is a foundational health decision.
- Monthly parasite prevention for fleas, ticks, and heartworm is considered standard of care.
- Early illness detection depends on knowing your pet's normal baseline behaviors and appearance.
- Preventive care typically costs less long-term than treating avoidable conditions.

Finding a Veterinarian Before Day One
One of the most effective things you can do before your pet arrives is identify a veterinarian. A first wellness exam — ideally within the first seven days — establishes a health baseline, reviews any records from a breeder or shelter, and creates a relationship you will rely on for years.
When evaluating a practice, consider location, whether the clinic sees your specific species (some practices focus on dogs and cats; others include exotics), and whether they offer emergency or after-hours referral services. The American Animal Hospital Association (AAHA) accreditation is one indicator of practice standards, though many excellent non-accredited clinics exist.
Bring any existing health records, vaccination certificates, or deworming history your pet arrived with. This prevents duplication and lets your vet build an accurate history from the start. For a broader picture of setting up your pet's environment alongside their health plan, see our guide on creating a safe, comfortable space for a new pet.
Core vaccine
A vaccine recommended for all animals of a given species regardless of lifestyle or location, because the diseases it protects against are severe, widespread, or transmissible to humans.
AAFCO nutritional adequacy statement
A label claim indicating a pet food meets the minimum nutrient standards established by the Association of American Feed Control Officials for a specific life stage.
Heartworm prevention
A monthly or periodic medication that kills heartworm larvae before they mature; far simpler and safer than treating an established infection.
Fecal exam
A laboratory test on a small stool sample used to detect the eggs or cysts of intestinal parasites such as roundworms, hookworms, or Giardia.
Life-stage nutrition
The principle that pets have different nutrient requirements at different phases of life — puppy/kitten, adult, and senior — requiring appropriately formulated foods at each stage.
Wellness exam
A routine veterinary visit for a healthy animal, focused on prevention, early detection, and establishing or updating health records rather than treating a specific illness.
Vaccinations and Preventive Care Basics
Vaccines prime the immune system to recognize and fight specific pathogens before exposure occurs. Core vaccines — those recommended for virtually all pets regardless of lifestyle — differ by species. For dogs, the American Animal Hospital Association identifies distemper, parvovirus, adenovirus, and rabies as core. For cats, the American Association of Feline Practitioners lists FVRCP (feline viral rhinotracheitis, calicivirus, and panleukopenia) and rabies as core.
Puppies and kittens typically begin a series of vaccines at 6–8 weeks of age, with boosters every 3–4 weeks until around 16 weeks, followed by adult boosters. Timing matters because maternal antibodies can interfere with vaccine response in very young animals.
Keep a Simple Vaccination Record
Ask your veterinarian for a written or digital copy of all vaccines administered, including the brand, lot number, and due dates for boosters. Store this alongside any records your pet arrived with. A complete record prevents accidental over-vaccination and is often required for boarding, grooming, or travel.
Non-core vaccines — such as leptospirosis in dogs or feline leukemia virus in cats — are recommended based on individual risk factors your vet assesses. This is why a relationship with a veterinarian, rather than a generic schedule, is so important.
Nutrition Foundations for a Healthy Pet
Nutrition is one of the highest-impact, daily decisions you make for your pet. Selecting a food formulated for the correct life stage — puppy or kitten foods differ meaningfully from adult formulas in caloric density, protein levels, and micronutrient ratios — is the starting point.
Look for products that carry a nutritional adequacy statement from the Association of American Feed Control Officials (AAFCO), which indicates the food meets established minimum nutrient profiles for its stated life stage. This is not a government certification, but it reflects an established industry standard widely referenced by veterinarians.
Feeding amounts matter as much as food quality. Overfeeding, particularly in puppies of large breeds, has been linked to musculoskeletal development concerns. Your veterinarian or a board-certified veterinary nutritionist can recommend appropriate portion sizes for your pet's size, age, and activity level. For daily feeding routines and schedules, our first-time pet owner's roadmap to daily care provides structured guidance.
Parasite Prevention: What Every New Owner Should Know
Internal and external parasites are among the most common health challenges new pet owners encounter, and most are preventable. The major categories to discuss with your vet include:
- Fleas and ticks: External parasites that can transmit diseases including Lyme disease (ticks) and cause flea allergy dermatitis or anemia.
- Heartworm: A potentially fatal parasitic worm transmitted by mosquitoes, affecting dogs more severely than cats. Prevention is far more straightforward than treatment.
- Intestinal parasites: Roundworms, hookworms, whipworms, and Giardia are common, especially in young animals or those from shelters. A fecal exam at your first vet visit can screen for these.
Never Use Dog Parasite Products on Cats
Several ingredients safe for dogs — most notably permethrin — are acutely toxic to cats and can be fatal even in small amounts from contact. Always confirm with your veterinarian which products are appropriate for your pet's species before applying any topical or oral parasite treatment.
Veterinary guidelines broadly support year-round parasite prevention rather than seasonal-only approaches, given regional variation in parasite activity and the relative safety of modern preventive medications. Never apply a product labeled for one species to another — some canine flea treatments are toxic to cats. Always confirm the appropriate product with your veterinarian.
Recognizing Early Signs of Illness
Knowing your pet's normal is the prerequisite for recognizing abnormal. In the first weeks home, observe baseline behaviors: how much they eat and drink, typical energy levels, stool consistency, and sleep patterns. Changes from this baseline are your earliest signal that something may be wrong.
Common early warning signs across species include:
- Decreased appetite lasting more than 24 hours
- Vomiting or diarrhea, especially if repeated or bloody
- Lethargy or sudden withdrawal from activity or interaction
- Changes in urination frequency or signs of straining
- Discharge from eyes, ears, or nose
- Coughing, sneezing, or labored breathing
When in doubt, call your veterinarian — many practices offer nurse triage lines. Early intervention is generally more effective and less costly than delayed treatment.
