We got out first corgi Tank about 2 years ago and he has never been a real big barker. Now we have our new corgi Gunni who is about 14 weeks old and every time we play with her or Tank plays with her, she gets aggressive and barks non-stop. She even challenges Tank and eggs him on and eventually he snaps at her.
When I pick her up and tell her "No" she growls and snaps at me, I have even tried putting her in the cage while I play with Tank calmly. It doesn't seem to be changing her behavior. Any suggestions???
