I know just how you feel Lorraine.

I once rescued a rottie from the shelter around here for one of the people on pt. She was supposed to go to a home the next day, but after I told her how she acted with my dogs (the rescue could have and probably would have killed one of my girls) so the lady didn't want to take her since she had puppies in the house.
Anyway, long story short this dog ended up getting along with some of the other dogs in the shelter and I felt the same way. But she just didn't get along AT ALL with my dogs.
So I think it just all depends on the dogs.

I think your letter was perfect.
