Hi everyone
Been a while since I have visited. I will refresh your memory: I have a brother and a sister (whom have been fixed) Border Collie and Blue Heeler mix? They are 17 months old now (teenagers). Sarah is the alpha dog. She is becoming aggressive towards Jagger over almost everything now.
How should I address this? Do I ignore or do I tell Sarah NO and shun her?
Open for any suggestions
Thank you
