Dr. Ann Hohenhaus takes you inside New York's Animal Medical Center, where more than 30,000 different dogs and cats are treated each year (in addition to every other animal you can think of)!

The doctor shares some general rules for keeping your animals out of the emergency room:

• "Garlic and its relative, onions, can cause anemia in dogs," Dr. Hohenhaus says. "There's a toxin in the bulb that damages their red blood cells and they become acutely anemic. So no garlic, no onions for the dog."

• "Another very dangerous thing that you have to worry about is raisins and grapes," she says, explaining that they can lead to kidney complications. "Since we don't know exactly why the grapes and raisins cause that, it's best to just avoid grapes and raisins all together."

Which foods does she recommend?

• "Rice is a great food and very digestible and very nutritious. That's fine."

• "Carrots get an A+ in my book. They're low calorie and they're crunchy and dogs love 'em. Mini-carrots, just whip them out instead of fattening dog treats."

Dr. Ann has one final "no-no," which turns out to be the source of Spike's pain. "Trash is terrible!" Dr. Ann admonishes. "Little Spike has bones in him, and nobody knows where those bones came from, but the most likely source for bones in a dog (if you didn't give your dog bones, which you shouldn't), is that Spike got into the trash or scavenged some bones on the sidewalk."

How is Spike doing now? Dr. Ann shares the good news:

"Spike had to have a specialist called in in the middle of the night with a special piece of equipment called an endoscope. And he went down with the endoscope, which has a teeny little camera on the end, and pulled the bone out of Spike and everything was fine and he went home the next day."
