Yes to both ...kinda

I've never had to put a dog to sleep but we had to put down 2 of our cats before, one had cancer really bad and the other was poisoned and too far gone

My parents adopted a GSD, Simba, from the pound when I was really little. He kept running off and would end back up at the pound. He did it so many times that they were going to charge my parents a fine. He ran away one last time and ended up at the pound and they never went back and got him. So they didn't really take him there but thats where he ended up
