I will say right away that all my animals are saved from death
Nothing will save anyone from death. It is inevitable.
Personally I try to keep all my "pets" outside and show them where to find food on the streets. I have dogs and cats and I do not try to intefere with their instict. The ones I keep with me are special cases, too young to be by themselves, abandoned, sick, etc.
Once I see them being able to be on their own, I release them. I am not a trainer nor a professional cat/dog "whisperer". My main concern is that they are food, have water, and are capable of living in these streets.
There are a lot of dangerous things for animals on the street, they will not live there for a long time. Where are you from?
There's alot of dangerous things everywhere for everything in life. Safety is an illusion.
That is not my concern nor my call whether they have long or short lives. I rather see a dog living in the streets happily for a short time then being tied up in some backyard being miserably for a long life.
But humans as they are think that jail is saving people from harm when in actuality it does more harm to society.

I have dogs not in the backyard on a leash, in the house. Thanks to the ability to eat, the development of their personality, they live much longer than on the street. They are written very happier in the street. And no one offends them, and does not come into contact with the car.
