Yes, they do. Since having Ladybug (our Miniature Schnauzer) I have had 6 surgeries, my daughter, and my husband both had dental surgery. She took care of each one of us every time. Just sticking to us like glue. Being very gentle and quiet.
We still have Ladybug, of course, and since adding Dazy to the family... I have MS. Now they both stick to me and lay right beside me or Ladybug in my lap when I am having an onset. They are also my stress-o-meters. When I am overly stressed, they will come and just lay on or by my feet or lap trying to calm me as they know that stress is one of my biggest MS triggers.
