I have two yorkies, Charlie (2 years old, 5 lbs) and Chloe (1 year old, 8 lbs). Two days ago they both started fighting one another very aggressively, and wouldn't stop until I pulled them apart. This used to happen rarely (once every three weeks or so), but now is happening 8 or 9 times a day. Charlie and Chloe always play fight, but this is different, very aggressive. I am genuinely concerned that they are going to injure one another. I have been separating them and disciplining them sternly (by saying NO! and holding them on their backs on separate sides of the room).

Have any of you had similar experiences as younger dogs matured? Or does anyone have suggestions on how o rectify these issues?
