I got Bella just under 4 months. She is a rescue, having spent the first wees of her life on the side of the highways and closed in a farm barn with cats and another dog. When I got her she really had huge trouble settling. Evenings were a nightmare. She wouldn't sleep and she would cry to be let out of my room so she could go outside and play. Now, as long as she gets her evening play session and toilet walk round the block, and her evening chew she very very happily sleeps in her couch in my room and is very happy to ahve a lie in if I'm having one. Bella used to play a bit rough with my friend's cats, but now she is the gentlest dog in the world with them, giving them kisses. They love her and come up to her when we visit. She would not walk on a lead but would freeze and refuse to move. Bella was always great off lead, but she walks very happily on the lead now, and is still great off lead. There is one thing that changed about Bella and it's the only thing I am not too sure about. She would never ever stand up for herself. She always lay on her back when greeting dogs and would not move until they were done sniffing. Since she had her season, if male dogs sniff her behind for too long she does have a fuse and will let them know she's had enough. She is still the most playful dog in the world, but does not enjoy inappropriate male attention. I am happy she is confident enough to stand up for herself, but I wonder if this is bordering aggresion sometimes.
