15 Things to Know Before Adopting a Large Dog

Thinking about bringing home a large-breed dog? I’ve been there — and let me tell you, it’s one of the most rewarding decisions you can make, if you’re ready for the responsibility.

Large dogs come with big hearts and big personalities — but also big needs. From food to space to exercise, everything’s scaled up. Here’s what I’ve learned over the years that might help you decide if a large-breed dog is the right match for your life.

Start with Space and Lifestyle

Large dogs need room — both indoors and out. If you live in a small apartment with no yard, you’ll be relying heavily on multiple daily walks and park visits to burn off energy. A fenced backyard is a huge plus, but not a must if you’re committed to giving them regular exercise.

And it’s not just physical space — big dogs take up emotional space, too. They love being close to their people and can develop anxiety when left alone for long hours. They’re not just “outdoor dogs” — they want to be part of the family.

Exercise Isn’t Optional

Daily movement is a must. Whether it’s long walks, hikes, fetch, or even agility training, large breeds need both physical and mental stimulation. Without it, boredom can turn into destructive behavior — think chewed furniture, digging holes in your yard, or non-stop barking.

When I got my Ridgeback, I quickly learned that a tired dog is a happy dog. Puzzle toys, obedience training, and structured playtime helped channel his energy in healthy ways.

Training Matters (A Lot)

A 90-pound dog pulling on a leash or jumping up to greet guests isn’t cute — it’s dangerous. Start training early and be consistent. Socialization between 3 and 14 weeks is crucial. Expose your pup to people, other dogs, and different environments to build confidence and reduce fear-based behaviors later.

Leash training and basic commands like “sit,” “stay,” and “leave it” are non-negotiables. And if you’re struggling, don’t hesitate to get help from a professional trainer — it’s worth every penny.

Budget for Bigger Everything

Let’s talk money: big dogs = big bills. Think:

• More food (and quality food at that)
• Larger beds and crates
• Heavy-duty toys (because flimsy ones won’t last a day)
• Grooming supplies — or professional grooming for thick or long-haired breeds
• Higher vet bills, especially as they age

Some large breeds are more prone to health issues like hip dysplasia, arthritis, heart conditions, and bloat. Regular checkups and preventive care are essential. Pet insurance can help, but always read the fine print.

Also, save up for emergency vet visits — those can sneak up on you fast.

Grooming: Don’t Skip It

Depending on the breed, grooming can be a weekly or even daily task. Brushing helps with shedding (which can be intense during seasonal changes), and don’t forget nails, ears, and dental care. Some large breeds also drool — a lot. If you’ve got a Mastiff or St. Bernard, keep a towel handy at all times!

Temperament and Family Fit

Not all big dogs are created equal. Some are gentle and calm (like Bernese Mountain Dogs), while others have more drive and energy (like German Shepherds or Huskies). If you have kids or other pets, do your research — some breeds are naturally more patient and sociable than others.

Always supervise interactions between dogs and young children, regardless of how "friendly" the breed is. Safety first.

Lifespan and Long-Term Commitment

Many large breeds live 8–12 years, sometimes less depending on health and genetics. Think about whether you’re ready for a decade or more of care. This isn’t just a weekend project — it’s daily walks, vet visits, feeding, training, and love. It’s a long-term relationship.

Are You Ready?

Having a large dog is a joy — but it’s also a serious commitment. If you’ve got the space, time, patience, and budget to meet their needs, they’ll repay you with loyalty, protection, and endless love.

Some popular large breeds to consider:

• Labrador Retriever
• Golden Retriever
• German Shepherd
• Doberman Pinscher
• Rottweiler
• Boxer
• Great Dane
• Mastiff
• Bernese Mountain Dog

Each breed has its own quirks and needs, so take your time, do your research, and talk to experienced owners or breeders before you bring one home.

Bottom line: large dogs aren’t for everyone, but if they are for you, they’ll change your life in the best way.
