Translation of dog in German

I'm looking to move to Spain in the summer and hoping to visit my friend in Barcelona before then so I was hoping to have the basics done by then. I've always wanted to learn another language, but we are not pushed enough in the US.
The city seemed to be small but busy and many building were new. It looked like a third world country village with four and five star hotels. The infrastructure was still bad, but one could see development.
In the late afternoon we took a taxi back to Cusco, which we shared with a nice Spanish couple. My wife who was mainly concerned with our sleeping conditions took the address of their hotel.
