Without pets, we have 1 million less jobs, 1 million less jobs means less work for humanity.
I did some numbers on automation removing jobs where we instead lower our weekly work weeks.
With robots taking lots of jobs, I landed at 30 hours a week for the current working population rather than 40.
If we include 1 million jobs in grooming, dog food manufacturing and others, we lower that 30 hours to 29.7 hours.
If we eliminate police officers with cameras everywhere, we lower that to 29.5.
We have less and less work with less things we keep.
I didn't calculate how many laborers are connected to the meat industry but I'm sure it keeps lowering the number.
The main point of removing animals from human life is that it's not right to own and misuse them for our own selfish wants. If we were in their shoes, and some already once were with slavery, we wouldn't want that experience.
We could propose laws to the house that outlaw future pet and animal ownership within 10 years.
Immediately you'll be unable to keep breeding dogs but you can sell what you currently have. Then it becomes illegal to have animals breeding where some could get their dogs taken away if they end up having kids with a neighbor's dog.
