Yesterday night I was foolish and kept trying to coax my dog to drink water because he hadn't drunk any water for hours even after his walk. I got frustrated and picked him up to put him in the room he stays in (he got excited at first because he thought I was going to put him on my bed but started whimpering on the way to his room). I didn't yell at him, hit him, or put him down violently on his bed, but it was probably the irritated manner in which I carried him there.. After I took him out this morning (7AM) he was whimpering when I petted him and then he walked away and sat a distance from me and continued to whimper. He also would not eat his food, so I had to hand feed him. Afterwards, I went back to bed and allowed him to sleep with me this time and he was fine but when I picked him up to put him on the floor when I woke again (the bed is high) he was shrieking and yelping although I was definitely not hurting him and I'm sure he has no injuries as he was perfectly fine before I acted so terribly. He has always been a timid dog ever since I've had him because he was abused at his previous home. He usually eats again at about 5PM but now he won't even eat from my hand, let alone his bowl. He puts it in his mouth and spits it back out and has not drunk any water so far today. I left the room where he usually stays but now he also has not moved from his bed whereas this morning he still followed me to my room even if he did not sit by me...
I apologize for rambling I just wanted to give some background. I have never EVER hit him, I have never hurt him (until now I guess) I love this dog more than anything in this world, more than myself.
Also, if I tell him to come to me he will come but whimpers when I pet him and then leaves to sit a distance from me again. I feel terrible even though I did not physically harm him. I just want him to eat and return to his former happy self, even his trot seems so slow and depressed now and I know I'm to blame. I know I should not have acted this way knowing how sensitive he is..
My main question is how do I make him eat and drink again? And how do I let him know that I'm sorry for acting how I did and that I would never hurt him? Please help me.
