Yes, the Labrador Retriever has a sleek, shorthaired coat that does not require much grooming and maintenance. However, this breed sheds heavily, and its fur sticks easily to furniture and clothing. The Labrador's shedding coat also makes it unsuitable as a pet for people allergic to dogs.
Lots of exercise is good for every dog, but the Labrador Retriever part will require a fair amount. If the "doodle" is from a full-size hunting poodle, then that part will call for a lot of exercise, too. If they whine and bark a lot, or chew up household items, then you can be sure that the dog needs more exercise and play.
Just brush the Labrador with the direction the fur goes. So down the back, down on the legs and chest, etc. Their ears and head do not need to be brushed, at the fur is much shorter in those areas.
Well it actually depends on the skin conditions sometimes. Short haired and long haired dogs shed, but I would say that golden retriever's shed the least. I have had one in the past and I didn't have much of a problem with her.
I think Pug, Basset Hound,Labrador Retriever,Thesebreeds are easy to train and do not need much grooming.
I see that you are asking about many dogs. Unfortunately, I don't know much about those breeds, but I do know that beagles and Labrador retrievers are excellent first dog. My first dog was a Labrador retriever and he was my favorite dog.
It eats too much or does not get enough exercise.
That depends on a number of factors, including how old you are and how much you exercise.
A pitbull would be physically stronger. Labradors are quite large, but they are not bred for the same physical qualities as a pitbull. Labradors are bred for retrieving game and companionship. Pitbulls are bred for catch-dog reasons. This requires greater physical strength as catch-dogs are sometimes used to take down cattle, hogs, and the like.
