Surreal, I'm so sorry to hear this news. 15 years is a helluva long life for a dog. I'll keep you guys in my thoughts tonight. Since it's business hours, try to get to a regular vet rather than an emergency vet who'll charge 3x as much. Ask about TPA as an option if it is indeed a stroke. I don't know that they give it to dogs, but it can be a godsend on people. Confidential protip to Zrazor: Take a stinky treat and put it to Ivy's nose. Then put it to your forehead like an idiot. Then, say her name and when she looks at you, give her the treat. Do this 100 times. Your dog's eyes will turn into lasers and she'll burn holes into your soul when you say her name.
