Hi everyone, I have a almost a 4 year old American boxer named Zeus, I have almost a 3 year old German boxer named zena. She is a resource guarder with her toys and we have managed that. Recently 2 days ago, I put her food bowl down first because they have tummy issues and I was making sure she didn’t vomit in the morning. Zeus came from outside and went to sniff her and she attacked him. We were able to separate them easily, they were fighting in the air, side mouthing and fighting, not biting down on one another. Now, for the past couple days when we are making their food, she has shown aggression towards him! Not us at all, just Zeus. We have now put her in the crate to eat and when we make the food. Zeus stays out of the crate to eat. I am getting a behaviorist involved and a trainer asap. Is this the right thing to do , or should I put her in a room and not the crate? Or should I put them both in the crate? He is not the aggressive one, he is scared to eat now because of her. He is 86 pounds and she is 60. They are big dogs. She has always been a little more aggressive then him in general due to being a female and almost pure German boxer. Am I doing the right thing?
