I learned long ago that as hard as it is it is even harder thinking about it every day till i had no choice but do what was right by the animal, i love them enough to let them go and i know some find that hard to believe but i have delt with 1000' of animals in my lifetime, it is never easy, i hold my breath and look away, i get a tightness in my chest till it is done , i use loppers to cull, it is fast i can just walk away till they have stopped kicken.
As sad as it is i have had to put down a few dogs in my life but watching them suffer was way worse after it was all said and done. I am still always left with that what if feeling

still knowing i did the best thing by them, it never gets easy and knowing when is even harder sometimes.
