Love the pictures, thanks for sharing.
Our 'horse' Caly who tips the scale around 75lbs used to sleep on the Queen size bed with my wife and I. I had to put an end to this after waking up several nights with me almost off the bed and the dog spread out snoring away. It took about a week of training to get her to not to come on the bed unless invited but so glad we did that.
The tough part of the training is being in love with an enabler
. Caly was doing great and I go away for a week on business. My first night home, I go into bed and guess who climbs in (hint: there were three of us). Doggie training 101, no means no, and it ALWAYS means no, even when you are too tired to get her off the bed.
