I think to answer the title - yes, if it is a true emergency situation, you have no choice. I have had mixed reactions from my emergency vets - while they did a good job with Pebbles the first time, they removed a pin in her leg, then a month later she lost the leg, and I can't help wondering if they shold have picked up on the arthritis, shortness of bone, muscle loss and inflammation that was apparent even to me weeks later. I can't blame them for saying she would have no furhter probs and then her be back 2 hours later cos of her paw turning under, I spoke to 3 vets that week, and none had heard of that kind of reaction!! The second time I just thought it was too expensive for what they actually did. But they are very friendly and helpful when you ring for an answer when debating if they need to see a vet or not.
