When Zig left my home he weighed in at 52 lbs, when he came back a year later he was tipping the scale at over 80 lbs! I was in shock because I had a hard time keeping weight on him because of how active he was when he lived with me. The extra weight was hard on Zig and his body- he had trouble running and keeping up, jumping into the car, and his coat had become very dry and flakey. Poor guy! I could also tell that he hadn't been worked properly, or at all! He had become very demanding and loud, which doesn't mix well with the tiny stubborn streak that was already running through him!
