Some prisons here in California are bringing dogs into the prisons, and they are teaching the prisoners how to train dogs, and how to groom dogs, and how to run kennels, etc. I fully support such programs.
When the prisoners get out of prison they can groom dogs, they can train dogs, they can run dog kennels, they can run community animal shelters, etc.
If you give someone honest skills that they can use to make an honest living, then everyone wins.
Salute,
