Oops I meant service dogs
It depends on what country you are in. In the UK service dog means police dog, search dogs, etc and assistance dog is the one for disabled people. In America service dogs are the ones for disabled people, no clue what the police, etc dogs are called
Goldens at shows are definitely not large but some goldens I have seen definitely fit into the large categoryHonestly I prefer extra large dogs or large dogs, I was surprised when someone told me that golden retrievers were considered large
There is no good why have categories dogs by size! Height doesn't really work and neither does weight
