He is a sweetheart completely. I got bud from a kill shelter in Clovis New Mexico. He has had a rough go at life you can tell but the thing is he has made maybe 1 groan while he was sleeping and that whine gsds have when they have a super duper big yawn just once or twice. It's very strange to have a dog that is so silent. I've had gsds before and they were all not really big barkers but I at least had heard it. I always said my last gsd had a grab a gun bark, if she were to bark you knew it meant something. But it wasn't to this extent of silence like bud my rescue. I mean I'm not complaining but more confused. I think it would be 4 days or 5 now I guess that I've had him. I live in Denver in a busy area we have go on walks he has seen squirls that he wanted other dogs mail trucks you name it, nothing got him going enought to let out a peep.
