I have a dog with a broken inside toe and this exactly what worries me if i have it amputated it will maybe put too much pressure on the other toes causing other problems .....
Nail wants cutting back to the quick to try and relieve any pressure/swelling around the joint and soak in ice water for first few days is what i would be doing. If its definitely dislocated pm me and ill tell you a couple ways that can make the healing process faster. Hope the bitch recovers for ya ??
