So my 7 month old puppy has wore me out. No matter how much exercise or training she NEvEr sits down. Nor does she let anyone in the house sit. When we do she barks at our face and will bite, (mostly my 9 year old because that is what gets me to get up. My breeder tells me it's because she doesn't respect me, my trainer tells me tonight she thinks my dog has anxiety and that's why she won't sit down, then she gets over tired and acts out with the barking and biting?? Recommended some natural anxiety meds? I'm at a loss, I spend every waking moment working with this dog and I am wore out. If things don't get better soon, I'm going to have to give her up. Please help!
