What factor causes significant fluctuation in Weimardoodle size?

Answer

The size of the Poodle lineage involved in the cross

The Weimardoodle's size category, which generally lands in the medium to large range, is highly subject to variation because of the diverse genetics contributed by the Poodle parent. The Poodle breed comes in three recognized size variations: Standard, Miniature, and Toy. When a Weimaraner is crossed with a Standard Poodle, the offspring are expected to be large, possibly reaching 45 to 90 pounds. However, crossing with a Miniature or Toy Poodle introduces the potential for a significantly smaller dog. Even in an F1 cross, the Weimaraner's consistent size can push the outcome larger than expected from the smaller Poodle parent, leading to substantial size unpredictability across litters.
