We as human beings make the conscious desicion to bring children into the world.
Animals are different in the fact that when the copulate, they did not go through the thought process of what it would mean to have babies. Animals are driven by instinct, not sentiment.
Humans are putting/forcing animals into controlled situations in which they are breeding, thus contributing to the millions of healthy adoptable animals being killed in shelters. The dogs won't stop and say to each other "wait, we better not do this...".
We make the decisions for the animals. Our guinea pigs do not tell us when they want to go to the vet or when they would like to have floortime or what veggies they want that day.
It is our responsibility to look after our animals, we are the ones breeding and killing innocent animals. It is not the fault of the animals being bred, but the fault of the people responsible for breeding them. It is impossible for the animals to know any better.
