<human>: Summarize the given text in a few sentences.

So yesterday we got a dog, she is a 1.5 year old Black Lab, Blue Heeler, Pit Bull mix. Up until then we just had two cats. When we got then in the same room the cats instantly started yowling, hissing, and raising their fur, which I expected. However, we tried to get them close and the cat tried to attack the dog, and the dog came right back at the cat. 

Now I know there is a adjustment period and that they need to get used to the smells, sounds, and sight of each other. The dog used to live with cats so she doesn't have a problem with them, but if the cats attempt to attack her again she is big and strong enough to kill one of them without trying. 

Is there a way to help the cats get used to her, or help speed the process up? I know its still very early but right now they are locked in a bedroom with a blanket that smells like the dog to get used to it, but any tips would be greatly appreciated.
<bot>: new dog in house, cats are not liking it, don't want them to attack each other because of dogs size and power, need advice on helping cats adjust.
