Thanks quiltingcandy. Thanks to your sister for her efforts. I think Buzz is our 7th grey. I gave up fostering them. I had 5 at one time because I couldn't resist keeping them. The ones I had were mostly seniors and were about 9 years old when I got them. Most people don't seem to want the older dogs and I feel so sorry for them. They've usually been in a home before and circumstances (death, illness, etc.) caused the owner to return them. I wish more people would be willing to adopt the senior dogs. They make great pets.
