I was wondering are certain breeds Therapy Dogs just by nature? I ask because my ''Jug'' Milford Albert a mix of Jack Russel and Pug, seems to know me well enough, and tries to comfort me, such as jumping on a chair next to me, wants me to hug him, in our backroom, he enjoys watching tv, and he acts as if he wants to say, put your favorite show on and relax, will want to watch tv and wants me to hold him, and just watches me in general always, doesn't socialize with other people or animals, acts busy in house. The last Jug I had named Mickey was the same way, yet my Miniature Schnauzer Magellan when I was growing up, was more rough around the edges, emotionally distant, but cared in his own way
