How to Choose a Puppy: A Practical Guide for New Pet Parents

Getting a puppy is one of the most exciting decisions you’ll ever make. It’s also one of the most consequential — for you and for the dog. Done thoughtfully, it leads to 10–15 years of genuine companionship. Done impulsively, it can mean heartbreak for your family and an uncertain future for the pup.

We see a lot of new puppies here at Dunedin Animal Medical Center, and we hear a lot of stories — about what went right and what people wish they’d known beforehand. This guide is our attempt to share what we’ve learned, so you can walk into this with your eyes wide open and find a puppy that’s truly the right fit for your life.

Start with Honest Self-Assessment

Before you fall in love with a photo on Instagram, spend some time thinking honestly about your lifestyle. Not the lifestyle you wish you had — the one you actually have on a Tuesday.

How active are you? High-energy working breeds like Border Collies, Australian Shepherds, and Siberian Huskies need hours of vigorous physical and mental exercise every day. A brisk evening walk won’t cut it. If your idea of a great weekend is quiet time at home, these breeds will make both of you miserable.
What’s your living situation? Apartment living is absolutely fine for many breeds — but not for every breed. Size alone isn’t the determining factor; energy level and noise level matter just as much.
Do you have kids or other pets? Some breeds are famously kid-friendly and gentle with other animals. Others have strong prey drives or territorial instincts that require careful management. Research compatibility carefully.
How much time do you have? Puppies require significant time investment — training, socialization, vet visits, exercise, and simple companionship. A puppy left alone for long stretches every day will struggle behaviorally.
Do you or anyone in your home have allergies? No dog is truly hypoallergenic, but some breeds shed less and produce fewer allergens. Talk to your allergist before committing to a breed.

Florida-Specific Consideration: Heat Tolerance by Breed

Living in Pinellas County means your puppy will spend most of its life in heat and humidity that many breeds weren’t designed for. This deserves real thought before you choose.

Brachycephalic breeds — those with flat faces, including Bulldogs, French Bulldogs, Pugs, Boston Terriers, and Shih Tzus — have significantly compromised airways and struggle to cool themselves through panting the way other dogs can. In Tampa Bay summers, outdoor time for these breeds needs to be carefully managed, and heat emergencies can happen quickly. They’re wonderful dogs, but Florida pet parents should go in knowing this requires extra vigilance.

Thick double-coated northern breeds (Huskies, Malamutes, Samoyeds) are bred for cold climates and can also overheat in Florida’s conditions. Short-coated, single-coated breeds with longer muzzles — Labs, Beagles, Vizslas, mixed breeds — tend to do much better in our climate.

Mixed Breed vs. Purebred: What You’re Really Deciding

The “mutt vs. purebred” question comes down to predictability. With a purebred dog from health-tested parents, you have a reasonable idea of adult size, coat type, energy level, and temperament. With a mixed-breed dog, there’s more variability — but often also what’s called “hybrid vigor,” and mixed-breed dogs may have lower incidence of certain genetic health conditions that affect purebred lines.

Neither is inherently better. A well-socialized, healthy mixed-breed puppy from a good rescue can be an incredible companion. So can a well-bred purebred from a responsible breeder. The question is always about the individual dog and the specific source — not the category.

Rescue and Adoption: What to Know

Adopting from a shelter or breed-specific rescue is a wonderful option — and there are more puppies available for adoption than many people realize. Reputable rescues will:

Have puppies examined by a veterinarian before adoption
Provide documentation of vaccines and deworming given
Ask you questions about your lifestyle and home to help match you with the right dog
Be honest about any behavioral or health observations

Be thoughtful with online rehoming listings (Craigslist, Facebook Marketplace, etc.). These can be legitimate, but they’re also common sources of sick puppies and misleading information. If you go this route, have the puppy examined by your vet as soon as possible after bringing them home.

Finding a Responsible Breeder

If you’ve decided on a specific breed and want to work with a breeder, take the time to find a good one. The extra patience is worth it.

A responsible breeder will:

Welcome you to visit and meet the puppies in person — in the place they were raised
Allow you to meet at least the mother (and ideally the father)
Provide documentation of health testing on the breeding parents — the specific tests vary by breed, but OFA hip/elbow certifications, genetic panels, and eye exams are common
Have a veterinary health record for each puppy, including vaccines and deworming
Ask you thoughtful questions about your home and lifestyle
Offer a health guarantee and a contract that requires you to return the dog to them if you can no longer keep it

Red Flags That Should Stop You Cold

Puppies available immediately, no waiting list (responsible breeders often have wait lists)
Multiple breeds available at once
Reluctance to let you visit or see where the puppies were raised
No vet records, no health testing, vague answers about the parents
Meeting in a parking lot to “make it easier for you”
Puppies sold at pet stores (these puppies overwhelmingly come from commercial breeding operations — puppy mills — regardless of what the store says)
Prices that seem too good to be true, or pressure to buy immediately

When Your Puppy Arrives: The First Vet Visit

Whatever the source — rescue, breeder, or a friend’s unexpected litter — every puppy should see a vet within the first week of coming home. Don’t wait until they seem sick. Here’s why: many puppies arrive with intestinal parasites, early infections, or other conditions that aren’t obviously visible but need attention. The first vet visit is also the time to establish a vaccination schedule, start heartworm and flea prevention, and discuss spay/neuter timing.

What to bring to that first visit:

Any vet records or vaccine history you received from the breeder or rescue
A stool sample (a fresh one, collected that morning in a clean plastic bag)
Your puppy’s current food and any feeding schedule information
A list of questions — there are no dumb ones

A Florida-Specific Reminder: Start Prevention on Day One

In Pinellas County, heartworm prevention isn’t a seasonal thing — it’s year-round. Mosquitoes that carry heartworm larvae are active throughout the year in our climate, and heartworm disease is genuinely common here. Your puppy should start heartworm prevention at their first vet visit, or as soon as they’re old enough (typically 8 weeks).

Leptospirosis is another concern worth discussing with your vet. Lepto is a bacterial disease spread through water and wildlife urine — and Florida’s wet season creates ideal conditions for it. Dogs that spend time outside, near water, or in areas with wildlife exposure are at risk. Ask your vet whether the lepto vaccine makes sense for your pup’s lifestyle.
