Viper's progress

Viper has shown so much progress, since we have had her. She has learned how to play with dog toys and loves squeaky toys. She runs in the yard with her toys in her mouth. She is starting to show trust and is following me around more. She still doesn’t approach me to pet her. I have to walk over to her, but once I start petting her she enjoys it and wants the attention. She can go up and down the stairs. She sleeps on her dog bed at night, and only gets crated when we aren’t home and during feedings. She doesn’t like to do her business on the leash. When we take her on walks we have to let her out in our yard immediately after. I guess she is a little shy about that stuff. We have two cats and she shows no interest in them at all. She appears to thrive in the presence of another greyhound, and follows our dog wherever he goes.
