It's been a real struggle in my house. I have the 3 Heeler/Dutch Shepherd mix dogs, all from the same litter. 2 are females, and they get into fights. Random fights. I have spent a lot of money at the vet for them, and no matter how much I want to feel like I can control everything, there are times that I can't. I joined Cali K9 for help. The training is fine but I'm struggling with trying to train 3 dogs at the same time. I have had dogs before. I've NEVER had a problem with training. Then I have never had 2 females from the same litter. The vet says they will never stop fighting, because they are from the same litter and always trying to be the dominant one. What should I do??
