My Mercedes is almost 5 yrs old and as of lately she seems to be really attached to me 24/7,,I love dearly but I almost step on her because she stays to close to me..like when i am cooking or doing dishes she is lying down right at my heels...had a check up when i got her rabies booster last month and she checked out fine.I am a widow so we are the only ones is the house. She was always a very hyper dog from day one and still is. When I have company over she has to always have something in her mouth and carries it around the whole time they are here. When I leave to do errands, etc she goes right to her crate and goes to sleep..when I return sometime she greets me and then goes back in the crate to sleep again!!! eats good , bowel and pee normal..what can be the problem if there is one? I love her to be by me but just worry that something is wrong and not being addressed.
