Riley the dog is a bit of an adrenaline junkie.
How do we know this?
Because he followed his owner into an airplane... and then followed his owner out of that airplane before it landed!!
This is sad! Why can't celebs keep their dogs in line???
Four dogs reportedly belonging to NFL star Joey Porter attacked and killed a neighbor's dog on July 2, leading to a citation for Porter.
An animal control spokeswoman said the Arizona Cardinals player was obviously upset about the attack and apologized to his neighbor.
The citation for failing to have the dog on a leash will likely result in a fine for Porter.
It wasn't clear how Porter's dogs got out of their kennel. A spokeswoman said Porter's dogs are large and appear to be half mastiff and half pit bull.
