Everyone Needs a Little Love

We have decided to open our dog loving home to a greyhound in need. His name is Big Fred and he is 4 years old. He has a little bit of separation anxiety and barks and whines when left alone. He came from an apartment with no other dogs, so we are hoping our Scout will keep him company until he finds a permanent home (which may be ours). He is very curious and playful. He has already taken to the new squeak toy I bought him. Scout does not seem very excited, but he never really shows much excitement. We are quite a sight walking down the road. Scout is 75 pounds and Fred is 78 pounds. I thought Scout was big, but Fred actually makes him look small.
