I'm new to bullys but not new to the dog world. Have had dogs all my life and none were ever allowed on furniture. I was a groomer, vet tech, and worked around some OB trainers off and on for years. I know for a fact that it can cause dominance issues and it has nothing to do with certain breeds. I have a neighbor whose golden started acting out when being on couches and beds growling and baring teeth. Once she stopped letting her dog do what it wanted to the dominance issue stopped. Of course consitent and persisitent training helped alot.
I had a cat years and years ago that was sleeping on my chest while I was asleep. I would wake up every morning all stiff and having trouble getting a deep breath. I finally woke up one night and figured out why I felt like crap every morning.My dogs used to be on everything until sheets started getting ripped and new furniture was purchased. Oh and it was cute when it was just Ginnie sleeping at the foot of my bed but once Beene joined the party it became a different story. Beene is a cuddler and waking up at night to a 70 pound dog laying spread out across your chest isn't very pleasant. It was cute but I would seriously wake up because I couldn't breathe! Luckily I was able to break that habit without much effort to be honest.
