We shopped around when we moved and found Mercy to be the cheapest and friendliest in our area. The staff are courteous and Dr. Jones is wonderful with animals. Our big dog had surgery to remove a tumor and the price was reasonable. They always explain procedures up front and don't make you feel like a loser if you can't afford something that isn't really necessary.
There is a Christian theme inside, which I like, but if that's not for you, then you may not like the decor...
