Choosing the right dog isn’t always easy—especially when many large breeds look remarkably similar. At a glance, you might not notice the differences. However, understanding the unique traits of each breed can help you find the best match for your lifestyle.
Below, we explore some of the most commonly confused large breed dogs—and show you what truly sets them apart.
Labrador Retriever vs. Chesapeake Bay Retriever
These two retrievers may look alike, but they were bred for different tasks. As a result, they behave quite differently.
Key Differences:
Size: 55–80 lbs (both)
Coat:
Labrador: Short, dense, and water-resistant
Chesapeake Bay: Wavy, oily, and thick for cold-water work
Temperament:
Labrador: Friendly, outgoing, and eager to please
Chessie: Independent, alert, and more protective
Lifespan: 10–13 years
Grooming: Weekly brushing is enough, although the Chessie’s coat may need more care
In summary: Labradors are ideal family dogs, while Chessies suit owners seeking a more assertive and driven retriever.
German Shepherd vs. Belgian Malinois
Although they both have a similar working-dog appearance, these breeds differ in temperament and intensity.
Key Differences:
Build:
Shepherd: Heavier and more solid
Malinois: Slimmer and extremely agile
Temperament:
German Shepherd: Calm, loyal, and good with families
Malinois: Highly driven, intense, and thrives on constant activity
Exercise Needs: Both need structure, but the Malinois requires even more mental and physical engagement
Lifespan: 10–14 years
In short: If you’re looking for a loyal family protector, go with the Shepherd. If you’re experienced and want a high-performance dog, consider the Malinois.
Rottweiler vs. Doberman Pinscher
While both breeds are known for their guarding instincts, they express their loyalty in different ways.
Key Differences:
Size:
Rottweiler: 80–135 lbs
Doberman: 60–100 lbs
Temperament:
Rottweiler: Calm, confident, and dominant
Doberman: Smart, affectionate, and energetic
Coat: Both have sleek, easy-to-care-for coats
Training: Early socialization is vital for both, although Dobermans may respond quicker to commands
As a result: Rottweilers make excellent guardians with a laid-back nature, whereas Dobermans are more alert and people-focused.
Due to their large frames and thick coats, these dogs are often mistaken for one another. However, their backgrounds and personalities differ greatly.
Key Differences:
Size: 120–180 lbs
Coat:
Saint Bernard: Short or long and tricolored
Newfoundland: Long, water-resistant, often black or brown
Temperament:
Saint Bernard: Slow-paced, gentle, and great with children
Newfoundland: Calm, strong swimmer, and excellent water rescue dog
Grooming: Both require daily brushing, especially during shedding seasons
To sum up: If you want a mountain rescue companion, the Saint is your match. If you live near water, a Newfoundland is a natural fit.
Great Dane vs. Irish Wolfhound
Yes, both are tall and elegant, but the similarities end there. These giants have very different personalities and needs.

Size:
Great Dane: 110–175 lbs
Irish Wolfhound: 105–140 lbs
Build:
Dane: Muscular and powerful
Wolfhound: Lean and shaggy
Temperament:
Dane: Goofy, sociable, and people-loving

Therefore: Danes make excellent family pets, while Wolfhounds may appeal more to those seeking a dignified and low-key companion.
Both breeds are giants with protective instincts. Yet, one is a bit more reactive, while the other is more laid-back.
Key Differences:
Size:
Bullmastiff: 100–130 lbs
English Mastiff: Up to 230 lbs

In conclusion: Bullmastiffs are better suited for protection-focused homes, while Mastiffs thrive as giant lapdogs with calm energy.
Final Thoughts: Don’t Judge a Dog by Its Looks
