Well, I decided against Tyson, as hard as that was. He's in a foster home, so he's safe and will get a home some day.
In the meantime I'm hooking up with a rescue out of Nashville and fostering for them. Much easier than trying to do it alone.
So, Saturday I pick up a 10 year old GSD who's owners decided they just didn't want to deal with him anymore. He was due to be euth'd with his younger 'brother' on the day the rescue sprung him. The younger dude is going to another foster until he finds a home. In the meantime I'll keep the older guy and then the foster lady that has the younger one will take the older guy and let him live his life out there with her!! :)
