My girls had a pretty bad fight

[T&Csmom]

I always felt that my younger dog, Candy considered herself to be higher ranking than Tashy, the older dog. Both females. they would squabble once in away, but nothing serious or couln't be stopped.

Yesterday however there was a stray cat in our yard, and this upset them both. For some reason when Candy darts past Tashy in excitment, Tashy growls at her. This infuriated Candy who then pounced on Tashy and had her by the neck for nearly two minutes till we managed to break them apart. It was horrifying, and Tashy was quite helpless. Fortunately no injuries to either dog, but since last night I've had to keep Candy in the garage. This it totally stressing me out. They were both indoor dogs, and it breaks my heart to isolate Candy. My house is not in a position to be separated so they can stay in two sections or whatever, so only other option is getting a crate for Candy, but can an adult dog used to running freely about the house be confined to a crate for most of the day? What should I do??? Totally in despair here :sad:
