Data are derived from our 2025 survey where owner-reported weights were categorised into six ranges. Both breeds are medium sized clustering in the 10 – 20 kg range.
As one would expect, the O’Connells are more variable in size than the minigroodles because they are a “breed in development’ rather than a First cross.

F2 O’Connells will always be more variable than the first cross as some will throw to the Cavalier and some to the Retriever, but as we select for our next generation from the dogs most like the F1 we are gradually reducing the amount of variation.

It will take a few more generations before they fall consistently within our desired goal of 12 to 22 kg but, while a small number of them are on the larger side of medium, they are still considerably smaller than Golden Retrievers where males are normally 29-34 kg while females are 25-29 kg.

The Minigroodles are more consistently in the 10-20 kg range and the outliers in the upper end of the weight range are largely descendants our half Lagotto Louie. We are using his much smaller grandsons and great grandsons these day.
