I have to agree "happiness really is a warm puppy". I am so glad you have your "little man".
My son moved to his house and took his two pugs with him. Sometimes, when he has time, he brings them over to stay with me for a few days. I miss them sooooooo much. And yes, when I wanted to pull the covers over my head and hide from the world, I couldn't, because when the pugs were here, well they kept me busy and even got me to taking small walks again. Meaning I actually had to go out of the house. Wow.. that was a biggie for me........
My son said he and his g/f will try to get me a pug for Christmas. I wish my son would move back home and just bring his pugs with him.
