An Ottawa family wants to know what kind of person would steal the wheels right out from under a disabled 10-year-old dog.

KCTV reported that the crime happened Saturday while Jeffrey and Lou Baker’s friendly, 50-pound boxer Sammy was outside their rural Franklin County home.

Sammy was outfitted with a special canine wheelchair last fall after losing the use of his back legs to a progressive disease. The wheelchair straps onto his body and helps him get around.

Franklin County Sheriff’s Deputy Jerrod Fredericks said it takes “a special kind of crazy” to commit such a crime.

The wheelchair turned up along a hiking trail near the Bakers’ home. The straps were intact, but someone removed a pin to make it easier to get the device off the dog.
