DH is away this weekend. He's normally at home with her most if the time as he WFH and this is the longest he's been away from her (3 full days and nights) since we've had her (she id from a rescue and is very anxious and totally bonded to him, she loves me but she LOVES him). I think she thinks he's not coming back bless her. First couple of days she was running to the door every time she hears a car like she normally does, but last night she sort of gave up on it and this morning she didn't even wake me up as usual just came down and sat sadly on the sofa on her own. She's eating, peeing, walking fine so I don't think she's unwell, just sad. He's back in a few hours so all will be fine but her little face is killing me. I'm fussing her but she's not interested. Do your dogs do this?
