Thank you all for your responses and super support. Since Andy is getting up there in years and physically I am not able to handle snarky dogs anymore I have decide that for now I will not foster until Andy is no longer with me.
Unless of course a foster comes along that I feel is appropriate to have in my house. One I just can't pass up. I got the feeling from her yesterday that she won't be calling me again to foster which is fine.
I did what I could.
