F1 vs F1B Goldendoodles: Do you know the difference? This article will explain what these terms actually mean and also give detailed information about the smart, adorable Goldendoodle.
F1 and F1B are just generation tags. A Goldendoodle F1 pup has parents of two different breeds, the Golden Retriever and the Poodle. In other words, it’s a hybrid dog. If an F1 Goldendoodle sire is mated to an F1 Goldendoodle dam, their offspring will be F2 and so on. However, this isn’t the usual procedure. Usually, an F1 dog will be bred to a purebred Poodle. This is called a backcross and is thought to improve certain breed traits like low or no shed. It can also result in other characteristics like a tighter curl of the fur.
F1 & F1B Goldendoodles: Size and Weight
The adult size of both types will vary by sex and the individual animal, but F1 Doodles tend to weigh between 50 and 75 pounds. Males are about 24 inches tall; females are around 21 inches. The size and weight of an F1B Doodle can vary greatly, depending on the size of the Poodle parent.
A standard Poodle parent can produce an F1B pup that will weigh at least 51 pounds and stand over 21 inches tall. A miniature Poodle sire will likely result in a smaller adult dog standing 17 to 20 inches tall and weighing somewhere in the 36 to 50-pound range
Lifespan and Age Comparison
Both the F1 and F1B Doodle have about the same lifespan, 10 to 15 years. Hybrid dogs can be expected to live longer than their purebred parents, and smaller dogs live longer than larger ones. Therefore, a Doodle with a miniature Poodle parent will likely live a bit longer than a Doodle with a standard Poodle parent.
Grooming, Shedding and Allergy
Golden Retrievers are high shedders. Poodles are not. The F1 hybrid dog tends to be rather hypoallergenic and is a good choice for those with allergies. However, there is no such thing as a truly hypoallergenic dog. All dogs produce dander. These are tiny flakes of skin similar to human dandruff. These flakes carry proteins that can trigger an allergic response in sensitive individuals. However, less shedding of fur also means less shedding of dander. In that sense, the dog is less likely to cause an allergic reaction.
When compared, the F1 Doodle will tend to shed more than an F1B. Both the F1 Doodle and the F1B require careful and regular grooming, but the F1B needs even more. The long, shaggy coat must be brushed regularly. The F1B Doodle is more hypoallergenic because it’s only 25 percent Golden Retriever. The other 75 percent of its genes come from the low-shedding, dander-retaining Poodle.
Temperament and Personality
The Golden Retriever tends to be affable, friendly and accepting of everyone. The Poodle tends to have a nervous, high-strung personality and is often suspicious of strangers. However, both the F1 and F1B Doodle often have mellow, gentle, calm temperaments, in spite of the Poodle heritage. There is not a great deal of difference between the two when it comes to temperament and personality. Both tend to be sweet, calm, loving dogs and make wonderful pets.
That said, the F1B Doodle might show nervous traits more akin to its Poodle parent. It’s very hard to predict, though, exactly how the genes will express themselves in a particular dog. Of course, training and kindness have a heavy influence, too.
