My corgi is 6 months old now and I really need some help with disciplining her correctly. Every where that I've read stated that it's normal for Corgi puppies to nip at ankles due to their herding instincts and you should use a loud "NO" or a loud noise to help correct this behavior. Since I've been trying that for about 4 months now, I've become a little desperate. It's not just the ankle biting (she's actually gotten a little better), my main issue is that she'll snap at you at certain times. These moments include when she jumps on the couch and we're sitting there already, she'll start to nip my arms. In the end, if I'm doing something she doesn't "agree" with, she snaps her teeth at me. If we discipline her, she basically looks at us with a "who cares" look on her face. We tried the short time-out and that hasn't worked either. She definitely has a mind of her own and I feel like I'll never have a well-behaved dog! Help!
