To answer the questions: Cincy'sMom: He is safe for now. To be honest I don't know what the local SPCA's policy is regarding length of time to keep a dog, etc. Karen: He loved Bud and Tash (more Tasha), the three of them played around quite a bit in the snow on the way back before I could get a leash on him, again, more him and Tasha.
I could go on and on pretending I'm not sure what to do, but I will have to admit to myself at some time tonight that I am going there tomorrow and very likely have a new dog!
