A hobby breeder is one who breeds not for profit (to cover some costs of their hobby), and under current legislation is someone who breeds less than five litters in any 12 months.
Anyone who breeds as a business has to be licensed by the local authority, so all these puppy farmers with horrendous conditions are either run without a license or they have one but no checks are made on conditions, so what is the point.
For example if I or most hobby breeders needed to be licensed we would have to have facilities such as separate kitchen facilities for dogs and humans, isolation kennels etc. Most hobby breeders choose to have their pups in their bedrooms and in their homes, this would not be allowed if you were a commercial breeder.
If we we all subject to the same rules only the commercial breeder would be in a position to bred, hardly what we really want.
