Ever since Sunday, my dog hasn't been behaving good. He used to love his crate, but now when we put him in it, he starts crying and barking. When we put the leash on him to take him on a walk, he bites me. Also, when we take him a shower, he bites everyone around him. he bites my mom so hard, even though she's wearing rough gloves, she still feels the pain and it burns her. I don't now what to do anymore and I can't cuddle with him unless I let him bite me. I'm begging you for help and I'm starting to lose hope in him. Thanks for all the help.
