F1 vs F1b sheepaDoodles

When breeding Sheepadoodles, breeders will refer to litters as F1, F1b, F2, etc. We breed both F1 and F1b Sheepadoodles. So what's the difference?

An F1 Sheepadoodle is a first generation doodle (where one parent is an Old English Sheepdog and the other is a poodle.) Our first-ever litter of Sheepadoodles was an F1 litter. The benefits of F1 doodle mixes are minimal to non-shedding and a low allergy risk. These doodles tend to have straight or wavy coats because of the higher percentage of Old English Sheepdog heritage.

F1b Sheepadoodles are second generation doodles where one parent is a Sheepadoodle and the other is a poodle. Because the percentage of poodle heritage is now 75%, the coats of these doodles tend to be wavy or curly. These puppies are more likely to have lighter frames than Old English Sheepdogs or F1 Sheepadoodles, but will still share features with both lineages.
