There are many different "types" of labradoodles. All labradoodles are unique in their own special way.
A first generation labradoodle (F1) is a cross between a labrador retriever and a poodle. My Maggie is an F1 labradoodle. She is as sweet as can be, and a real princess. She is actually miss priss in our house!
A second generation labradoodle can be one of two crosses.
A backcross labradoodle (F1B) is a cross between a first generation labradoodle (F1) and a poodle. Madelyn is considered an F1B labradoodle.
The other second generation cross is rare. It is referred to as a true F2 labradoodle, and is the product of two first generation labradoodles (F1 x F1). There can be many inconsistent coats with a true F2, and that is why an F1B is more widely known.
An American Multigeneration Labradoodle is the result of breeding labradoodles to labradoodles further down the line.
An Australian Multigenerational Labradoodle has ancestors that go back to the foundation breeders in Australia. Mickey is a true Australian Labradoodle.
An American-Australian Multigenerational Labradoodle is the result of incorporating new fresh bloodlines into the Australian Labradoodle. Madelyn is bred with a true Australian labradoodle to further the gene pool. Molly is the result of this breeding and she is an American-Australian Multigenerational Labradoodle.
There is a place in this world for all types of labradoodles, as everyone has a different preference.
The labradoodle comes in 3 different sizes.
A MINI sized Labradoodle ranges from 14-16 inches. They are typically 15-25 lbs.
A MEDIUM sized Labradoodle ranges from 17-20 inches tall. Medium labradoodles weigh 30-45 lbs.
A STANDARD sized Labradoodle ranges from 21-25 inches tall. They range in weight from 50-65 lbs.
There are many different coat types that are unique to the labradoodle. These are the most general descriptions.
A hair coat is most commonly associated with the F1 labradoodles, although it is just as possible to obtain a hair coat with a multigen labradoodle. These coats are considered "throwbacks". There may be minimal to heavy shedding associated with the hair coat, although it is possible to have a dog with a non-shedding hair coat.
A fleece/borderline coat boasts long loose curls. This coat can be very soft, but might change during the puppy-adult transition stage. Fleece coats are generally non-shedding and easier maintenance than wool coats. A fleece coat is generally good for allergies.
A wool coat is a tight poodle curl. This type of coat is very thick and requires a lot of maintenance if kept long. The wool coat is non-shedding and great for people with allergies.
Black
A black dog does not have lighter patches, such as large silvering patches on the back and legs. Usually, black dogs do get brown muzzles or brown hughes. A few silvering hairs is also common.
Silver
Silver dogs have the "greying" look. They are born black, but a true silver, will show signs of silvering on the face as they get a bit older.
Chocolate
A chocolate dog has a rich true chocolate coat as a puppy, but will often fade as they get older due to sun. However, an indicator of a true chocolate is the base of the coat. The base of the coat should not be faded, but remain a deep chocolate. Mabel is pictured below and you can see the uniformity in her coat. She is a deep chocolate coloring!
Cafe
Cafe is faded chocolate throughout the entire body. Even the base of the coat will be light. Lewis is pictured below and he has a much lighter coat than Mabel (chocolate pictured above). Lewis has a lighter undercoat as well, which is consistent with the cafe coloring.
Parchment
A parchment is born a lighter chocolate color and begins to fade early on. The body of a parchment dog will appear greyish. Full color is not reached until the dog is between 2 and 3 years old. Madelyn is a parchment color.
Red
True red is very similar to rich true chocolate because red dogs often fade in the sun. Again, a true red will have dark roots. Lello pictured below is a true red. She will not fade as she ages either.
Apricot
An apricot dog has shading from cream-red on body, and usually darker ears. There are many variations of apricot (light apricot to dark apricot). Here are a few pictures to show the differences in the apricot coloring. 

Cream
A cream dog is very similar to a white color just a few shades darker. They do not have any darker colors on the ears or tail. Sadie is a gorgeous cream colored doodle. Her color is very uniform throughout her entire body.
White
A white dog does not have darker ears. They are a solid white color. The picture below is a white standard poodle named Joey. As you can see, he has no highlights to his fur, and the ears are not a different color from the rest of the body.
