I'm not generally soppy over Eric although I love him dearly but at times he is so sweet even I feel mushy over him.
Today was grooming day, Eric hates it (but manages to behave there and they seem genuinely happy to see him so all good) and he sulks from the minute you mention "going to see the ladies" 
He needs carrying into the car whereas he usually leaps in and them sits with his back to you. He refuses to get out of the car so end up carrying him in and putting him down where he alternates between hiding behind my legs or standing on two legs to get me to pick him up.The groomer then has to carry him through because he refuses to walk.
Three hours later I go to pick him up and can hear him from the car park crying and howling. I walk in and he gets even louder and ask if he's been ok to be told he'd heard the car ( he recognises ours from every other car at home too) They have his next appointment ready because he goes berserk when they bring him through shrieking with joy and running circuits.
Nobody else but Eric has ever been as happy to see me each and every time he's been left tbh. There's no wonder he has a special spot really.
What do you dogs do that melts your heart?
