It is not uncommon for dogs to need extractions, particularly in small breeds. What breed do you have?
One of my dogs (mini schnauzer) recently had a dental cleaning, which included a full mouth X-ray. Ultimately he had 6 teeth pulled (bottom incisors). Visually, you wouldn't have known those teeth needed to be removed (totally clean, not fractured, only one was slightly loose). But the X-ray revealed that there were pockets in the gums and possible root damage. They did it to preserve the canines. If gum disease is allowed to spread it will claim more and more teeth.
The only reason I can think that they would do an X-ray for cats and not dogs is because cats have a lot less teeth? So they want to be more sure about extractions? Not sure on that rationale. I do know that dogs have a lot of teeth and they can get by just fine with a few extractions if it keeps the mouth healthier.
