Lil Bear slept with me in my bed from puppyhood till age 4 then started sleeping with my parents in their king bed which is her post everynight since my mom got sick 2 yrs ago, she has a bed on their bed but usually is sleeping under the covers with mom (she's the heater). Lil Bear not sleeping with me anymore was one reason I wanted my own pup.
When I got moose I let her sleep with me and she slept curled above my head, then I starting seeing the "rice worms"

and she was deligated to her crate next to my bed. For a couple of months I have been trying to get her to sleep with me in my bed again since she is good about going to her pad at night, but she has had no part of it and would go into her crate and sigh Loudly till I closed the door, but after I got home from the hospital (appendix surgery) she has been in my bed every night curled up by my neck, she found she has gotten too big for ther pillow and mom won't give it up
PS both of ours are bed hogs when they are really sleepy and with me still having a twin bed it's a battle as to who gets more space
