I just adopted a female Bullmastiff who has some serious physical health recovering to do. I am used to big dogs having had a Great Dane who recently passed away. My question is, are Bullmastiffs typically wanting to be glued to your side or your lap? She is a big lovebug but it is difficult to get her to not push into me physically. She has little training but has learned sit and come well. With her health issues I don't want to push her hard on training. Thank you for any insight!
