Sudden fights between dogs
hey guys, my friend whos has 3 dogs, Rex(11 month Male GSD), Kale (10 month Male rot) and Athena 1 year ( Female GSD)
A few weeks back Rex started showing signs of aggressive such as toy aggression. Now it has become worst to the point where Rex just randomly come forward to Kale/Athena and will start a fight. Kale and Rex fight more for some reason and they have scars and such. It strange because they grew up together. My friend is thinking of re-homing rex because of this issue.
Any help to solve this problem would be great!
Rex and Kale: Not netrued
Athena : is spayed
