This happens fairly often, according to my husband.
On evenings when I am working and he is home, Scout will continually make howling and yowling noises throughout the evening, and appear restless. He lets her out; she barks and wants back in. She comes back in; she yowls and paces and bothers him.
Basically, according to him, she makes a lot of noise and won't leave him alone. Just the other night he pointed to her and said, "I think the problem is that she doesn't like me! Because for three hours she has been pestering me, and now .... when you get home.... look!"
She was chewing contentedly on a nylabone. She looked very peaceful.
I have no idea what is going on. Does anyone else have any ideas?
