You were obviously talking about traditional pets, not service animals.
The service animal industry is also largely problematic and exploitative.
Rescue animals can serve as service animals in a large portion of cases anyways, you don’t need “purebreds” to work as herding animals, bomb detection animals, anxiety-comfort pets, guide pets for the blind, etc.
I know multiple people who have service/working animals and my spouse and I both work in the pet foster community, so no not uninformed.
