Hawaiian Humane Society believes that the breeding of pets should only be done if responsible guidelines to ensure healthy animals are followed and there is a certainty that the resulting animals will be placed with responsible owners. We caution would-be pet owners against viewing breed registries as a guarantee of good health or behavior.

The Hawaiian Humane Society opposes puppy mills, which are high-volume commercial operations that prioritize profits above animal welfare. Puppies produced in puppy mills are more prone to disease due to poor nutrition, inadequate medical care and the stress of being shipped long distances at a young age. Puppy mill breeders generally ignore the behavior traits or physical problems of the parents, leading to the perpetuation of congenital disorders or undesirable and sometimes even dangerous behaviors
