My Charlie is a much different puppy than my Gracie was. I am so frustrated with him. I love him so much, but I seem to spend more time yelling No or being upset with him than loving him. He is constantly barking or biting. He has plenty of chew toys but doesn't want to use them. He is always biting me, mostly my hands, feet, arms. Tonight I heard something funny in the kitchen...walked in and found him chewing on my kitchen chair. I was so angry. He destroyed it. I can't afford this and I don't know how to fix it. Gracie never did these kinds of things. I use the bitter apple spray on the baseboards because he chews on those too. He bit me so hard the other day (not being mean, just playing) and made me bleed. I want to snuggle and love on him, but he hurts me. Gentle swats on the butt don't seem to affect him. Putting him in a time out in his crate doesn't seem to work either. I just cry because I don't know what else to do and then he kisses me. Please help.
