Yes, it is terrible.
Pet owners help perpetuate a cruel and inhumane industry.
The fact that you own rescue dogs, and are thus aware of the surplus, but can't accept that this cruelty is caused by the industry that you support is just run of the mill cognitive dissonance.
See, I can't do anything about "pet ownership", whatever that is. I can't do anything about over-breeding. I can't do anything about the thousands of dogs killed or living in pounds.
Oh wait! Yes I can! I rescued three of them. They have happy lives with us and our friends and each other now. A big safe yard with squirrels to chase, good food (not the squirrels!), soft beds (they're all on my bed right now), laps to sit on, baths and teeth brushed, no fleas (usually), and not getting eaten by raccoons or caged and killed in a pound.
Fucking terrible, isn't it?
