  If it's anything like human IVF, the eggs would need to be present, meaning the dog would need to be ovulating, meaning she would be in the middle of a heat cycle and they don't usually spay in the middle of a heat. 
Not to mention the surrogate dog would have to have fertility drugs and other drugs to trick her body into not rejecting the blastocysts.   
I've had IVF 8-9 times, so I'm pretty familiar with the human side of it.  Not as sure on the dog side. 
I do know it's rarely done.   AI is the preferred method, but still a dog has to be ready (in heat and ovulating) to properly AI.
