So, my family and I saw this dog http://www.lematin.ch/faits-divers/c...333?comments=1 in the newspaper where we live. It says that this un named toy poodle was put into a plastic bag and thrown onto the streets to die. A nearby bus driver saw him and saved him. They think that he's about 5-6 years old. My family and I immediately fell in love with him. My mom contacted the shelter where they're keeping him and asked them if we could possibly meet him.
Now, they say that he's obviously been abused, so he could have issues. We also own a 2 almost 3 year old toy poodle ourselves named Coco. She's very sweet, but a little bossy when it comes to new dogs. So, I was wondering, are we doing the right thing by adopting him? Do you think that he'll be happy with us even with another dog in the house? Should we keep Coco away from him while he gets used to our place?

P.S my sister and I have already named him Louis ( pronounced lewi).
