I also get a empty feeling in my stomach when I have
to leave my dogs and go to work.

I always new my dogs loved me, even though they
are pretty independent.
2 weeks ago, I went on a 2 day camping trip with
my immediate family. My husband had to work and
he stayed home with Pepper and Sheba.
(I took Rocky with me)
When I returned home, my husband said
Sheba was misrable.
She refused to eat, and only ate the 2nd day when
he let Pepper out by her food bowl.
She low growled at him when he tried to give her
pills and she passed up and down the house
for 2 days.
Needless to say, when I got home she was one
happy camper that everything was back to normal.
