Luciano from Bethesda, Md., is a 130-pound Rottweiler, whose appetite has gotten him into some trouble with his owners, Deedee, a realtor, and Chris, a documentary photojournalist. The worst offense: when he ate Deedee's engagement ring.

At a cost of $300, an X-ray confirmed that Luciano had eaten the precious ring.

To get her engagement ring back for her wedding, Luciano's owner had to sift through many of the pup's "deposits."

Fred, a beagle-whippet-Lab mix from New York, found herself homeless in Mississippi after Hurricane Gustav. Jen Lee, a real estate broker, and Luke Miller, a manufacturer, adopted Fred and learned she was a "curious" pup. In her first week in New York, Fred ate grapes, which can be poisonous to dogs. The vet had to induce vomiting. Fred later ate chocolate, which earned her another trip to the vet. Then there was the ingestion that put her in much more danger than before, glue and a cell phone charger.

An X-Ray shows the giant glob of glue with small, sharp metal wires from the cell phone charger that Fred ate mixed in. It posed an immediate threat to Fred's stomach and intestines, leaving surgery the only option. The bill totaled more than $3,500.

Soon after being adopted from a rescue group last year, Bogie, a Saint Bernard from Anaheim, Calif., started having seizures. The vet diagnosed him with epilepsy and was able to control his seizures with medication. One day, while taking his epilepsy medicine, Bogie swallowed the spoon it was on.
