Hi. I have a foster (who is now my dog, I can't give him up)who came to me as a bag of bones. He was so skinny and had food issues for the first few days. Now my daughter (11) and I can put our hands in his bowl while he is eating with no problems. I wouldn't attempt to take people food from him but, that is not because of anything he did to me, just my fear because of how he was when I first got him. Last night my husband was filling the dog food bin and the dog decided to eat out of it. My husband told him to get out and he didn't so my husband pushed his head out and he bit my husband. (Small puncture wound on forearm) then my husband grabbed him by the collar and shoved him to the corner. The dog tried to bite him again and growled but was not able to bite because he was being choked with his collar by my husband. He was trying to get away, scared to death, his tail was all the way between his legs. Then my husband picked him up and put him on the floor on his side really hard then picked him up and put him in the crate. After this the dog was completely submissive to my husband. When he came back out of the crate he laid next to my husband and rolled onto his back. When my husband petted him he laid his head on my husband's lap and licked his cut. I could have killed my husband for reacting that way and being so mean to him, and I feel like I betrayed my dog by not protecting him. What is the proper way to react when a dog bites? Also, is the reason that my daughter and I can put our hands in his bowl when he eats because we are the ones that feed him? My husband gives treats and table scraps but I am the one who fills the food bowls. My daughter and I are cautious with him when he eats because of the way he reacted to us when I first brought him home. He can eat with my dogs in the room however with people food, he will chase them away and if they don't go he will pin them down, will not bite them and will instantly let them up when I tell him no. The owner of the rescue is telling me to put him down, luckily it is not her decision but mine and I will not do that. Anyway, any advice on how to correct this will be greatly appreciated. Thank you!!

I'm a complete newbie and learning from everyone on this board. So I might not have the right answer and anyone can correct me. But my first thought after I read your post was I would one, stop feeding him "people food" and stop feeding him from the table. From my understanding he should only eat was given to him in his food bowl or treats when you are doing OB training with him. Just a few of my thoughts.

You are saying that he's aggressive with high-value items (fresh food)?

Is he fed in his crate?

Food Aggression

Above is a link from a recent discussion on the same thing.

How long have you had him, and are you working diligently with Groundwork to Becoming Your Dog's Pack Leader?

Also, "cautious with him when he eats" sounds like you tiptoe around him.

This reinforces everything that you don't want to reinforce.

He is fed in his crate meaning there is always a full bowl of food in his crate but, I have food bowls for my other dogs (I have 6 others that are mine and one other foster)in the kitchen which he prefers to eat out of. He rarely eats the food in his crate. He does have some crate aggression, not with food, he just gets scared i guess and he barks and growls and sometimes lunges. Before last night I have never seen any aggression from him outside of the crate.

These are a few articles on here that I think you & your husband should be reading.

Im not going to get into how I think you're husband probably went a bit over-board. at least IMO he went too far with the dog.
others may have a different view.
Just know that I doubt the dog acted submissive to your husband once he came out of the crate because he respects him as pack leader, but more due to the face that the dog is now AFRAID of your husband.
Also there's some info that you left out.
How old is the dog?
Breed of dog?
How many other dogs are in the household?

Edit: i see some of my questions were answered. But honestly read those articles. They will help you with most of your problems.

I think that your husband handled the situation, he had a wrestling match with a biting dog and won. Was the dog hurt? Doubtful. Do you think that he will bite your husband again? I don't think so. The dog sounds like he now views your husband as alpha (that's a good thing). It also sounds like you need to become alpha or you will eventually get bitten. You said that you were scared of him and wouldn't take people food (high value food) away from him.
How about being upset that the dog was so mean to your husband and you didn't have him trained to respect people and not bite them.
If this dog bit your husband he will probably bite you or your daughter if you aren't "cautious with him when he eats". You need to do pack structure work with this dog.
You also need to control his aggression with your other dogs, you should allow NO threats or chasing away.

I guess I do tip toe around him with certain things (eating). An example is the other day my daughter dropped a raw egg on the kitchen floor. Sen went to lick it and my daughter went right down to take it but I stopped her before she could because I don't know what his reaction will be. So, I stood right next to him and said no Sen and he ignored me so I put a papertowel over the egg and picked it up without incident.
