Letters and Numbers – What do they mean?!

When a litter is advertised, you will see a letter and a number next to the litter’s breed (Such as F1, F2 or F3).

The letter ‘F’ stands for Filial, which denotes the offspring of a cross. The number corresponds to the litter’s generation.


F1 Generation

Describes the cross between two separate pure breeds. For Groodles, this would be the Golden Retriever and the Poodle (either toy, mini or standard).



F2 Generation

Describes the cross between two F1 generation Groodles.





F3 Generation (not commonly used)

Describes the cross between an F2 and an F2. While generations can continue indefinitely, an F3 or higher-generation Groodle crossed with another F3 or higher Groodle is generally referred to as ‘Multi-Generational’.




Groodles come in two different sizes, which is dependant on the type of Poodle used in their heritage.

Miniature: Height can vary between 35cm and 48cm at the shoulder. Average adult weight can be between 15kg – 23kg.

Standard: Height can vary between 50cm and 70cm at the shoulder. Average adult weight can vary between 25kg – 45kg.

Health Testing

Health testing is carried out on ALL of our parent dogs (being either Golden Retrievers, Poodles, or Groodles), and this is achieved by collecting cells and saliva from a cheek swab. The swab sample is then packaged and sent to an independent laboratory where a health profile is completed. We ensure our breeding dogs are checked against the following:

Golden Retrievers

– Progressive Retinal Atrophy
– Degenerative Myelopathy
– Progressive Rode Cone Degeneration
– Muscular Dystrophy – X-linked
– A Locus
– K Locus

Poodle (Standard)

– Degenerative Myelopathy C- DGMY
– Neonatal Encephalopathy C-NENY
– von Willebrand’s Disease Type I C-VWD1
– Renal Dysplasia C-RDSP

Poodle (Miniature)

– Progressive Rod Cone Degeneration – PRA C-PRCD
– Globoid Cell Leukodystrophy/Krabbe’s Disease C-GCLY
– Renal Dysplasia C-RDSP

Poodle (Toy) 

– Progressive Rod Cone Degeneration – PRA C-PRCD
– Renal Dysplasia C-RDSP

Groodle testing is a combination of both of the above.

Hip and Elbow Testing

Our parent Groodles are Hip Scored using the PennHIP scoring system. This radiographic procedure is carried out by selected Veterinarians at Greater Springfield Veterinary Hospital, who are specially qualified in this method of testing.

Our parent Groodles also undergo radiographs of their elbows prior to breeding (as the elbow joint is often commonly affected by genetics). The images are then sent to an independent radiographic imaging specialist for an opinion on whether or not conditions such as elbow dysplasia exist.
