From reading your other posts, your dog was rescued and abused before you got him.
I think by crating him and muzzling him, he will feel threatened and act out accordingly.
Your son could remind him of a former owner who was not kind to him and by your son's behavior towards him it just reinforced it. Dogs do not forget people who are mean to them or intimidate them. Try going for walks (all 3 of you) maybe have the dog on a leash while sitting around or watching TV and play ball or some sort of game. Let the dog get used to your son, but your son has to not react violently to the dogs aggressiveness. Put one of your son's (old) shirts in the dogs kennel to let him get used to his smell, and have your son feed him a meal and give him treats.
These are just some suggestions, hope something helps... |
