I have to girls...when we first introduced each other, my older one (Happy) was super nervous. She was panting and drooling all over the house. And then, it turned into mild fighting. Not so much fighting but very rough play. One time, Happy grabbed Lily(the younger one) by the ear. And now, they're inseparable. It took almost a year. It's still a work in progress, tho. If I say "brush," both will run and try to sit on my lap. Yeah, I thought it was super funny that they like to be brushed. So, I throw a toy so that one of them is playing with the toy while I'm brushing the other. Sort of like multitasking. Lol. Brush with one arm, throw toy with the other, praise Happy, and praise Lily.
I agree with Maximo. Good to redirect their attention
