Characteristics Of A Rottweiler

The Rottweiler is a large-sized dog of the Working Dog group. Males reach 25 to 27 inches in height and 93 to 135 lbs in weight. Females reach 22 to 25 inches in height and 80 to 100 lbs in weight. They have a lifespan of about 9 to 10 years.

The bad reputation of Rottweilers especially in the news and media is pretty well-known. However, they still have a lot of loyal fans from all over the globe. Rottweilers rank 8th in the United States according to the American Kennel Club. They are an industrious breed and can be seen working the floor as police dogs, therapy dogs, and seeing-eye dogs.

Characteristics Of A Labrador Retriever

The Labrador Retriever is a large-sized dog of the Sporting Dog group. Males reach 22.5 to 24.5 inches in height and 65 to 90 lbs in weight. Females reach 21.5 – 23.5 inches in height and 55 to 70 lbs in weight. They have a lifespan of about 10 -12 years.

They are America’s favorite dogs, topping the breed rankings year after year. This ball of energy and sunshine tries really hard to bring a smile to people’s faces, after all. This lovable breed is a great package of friendliness, athleticism, and affection. Great in the home and in the great outdoors, big active families do not have to search far and wide for a companion.

The Rottweiler and Lab Mix Size Difference

These distinct breeds have some considerable differences when it comes to stature. Here are some of the factors that contribute to this range of sizes you need to be aware of before buying or adopting lab rott mix puppies.

While both dogs are classified in the large size dog group, their heights can have a significant gap of up to 3 inches. Even with this slight difference, it’s unpredictable what the height of the mixed breed will be. It is better to make allowance for taller dogs.

If your mixed breed also inherits the Labrador love for activity and adventure, you want to make more space in your home for just that. It might be tough without a nice park or safe roads in your area, but we are sure your dog will find a way.

It should be mentioned that it is important to pay attention to the bone development of your dog. Large-sized dogs have the tendency to have shorter lifespans than smaller breeds, and many have bone deficiencies to blame for the loss of quality of life. The Rottweiler is predisposed to hereditary diseases that affect their lifespan. Pay attention to bone health by providing nutritious food and taking your dog to the veterinarian.


As you can see from the numbers mentioned in the characteristic above, the weights of the two dogs are very different. The Rottweiler is a very heavy dog. Their difference can go up to 60 lbs. That is no small amount! It’s definitely a significant amount of weight for your household to support.

It should be noted that Rottweilers can grow really tall and have a tendency for obesity – both factors not obvious from birth. You need to keep that growth spurt in mind if you have a small house or do not have plans of expanding the dedicated space for your dog. You just might be surprised with how much the Rottweiler Lab mix size could grow!


The Rottweiler and the Labrador, while having different builds, have a similar large size classification due to height. What makes up for all that difference on the weighing scale?

The Rottweiler has a much more muscular build. You can see this in the power required of them in the jobs they are assigned: pulling carts, guarding homes, and rounding up criminals.

On the other hand, the Labrador has a slender, athletic build. They are the ideal dog for sporty people because of their disposition towards fun, exploration, and activities.

With these factors in mind, the rottweiler lab mix average size could be in-between any of the given parameters for either breed.

Of course, it should be emphasized that a mixed breed does not guarantee any outcomes. Despite the advancements in the field, and cross-breeding displaying some incredible achievements, there is still a lot of unpredictability when unknown factors come into the mix. You should temper expectations, and love your pet for all that they are and become!
