An illustrative medium-to-large companion dog, of the Labrador type, used as a reference point to test whether a size or breed limit is arbitrary.
Benchmarked at approximately 20 to 35 kg and up to 60 cm at the shoulder, comparable to a Labrador Retriever, Golden Retriever, or Standard Poodle. It is a reference point, not a breed list.
A policy that would exclude a dog within or below this benchmark, without a specific and stated justification, is presumed to be unreasonably restrictive.
