I would say U need 2 get him another buddy...
We got a full blooded german rottweiler"sp?" when my daughter was born and they grew up together "daughter being only child" so, they were like best friends. well Kenya "ROTT" died about four months ago she was about 9 1/2 yrs old.. my daughter cried for about 2 weeks straight and then she stopped now she set on getting a Pugg "sp?" So, I'm getting her another dog. She told me she needed another buddy to hang out with @ the house..
