KANSAS CITY, Mo. — A dog that attacked a smaller dog at Heritage Park in Olathe last week will be quarantined for 10 days and required to wear a leash at dog parks in the future, according to Johnson County Park Police.

Park police say they found the owner of the dog, who was not the person watching it at the off-leash dog park area on Thursday.

The owner has not been able to provide any up-to-date vaccination records for the dog, park police said.

Mitch Wiles, the owner of the 10-pound Cavamalt that was attacked, said he will have rabies treatments as a precaution.

While trying to get the pit bull-type dog off his Cavamalt, Ranger, Wiles said he put his hands in the other dog's mouth.

After the attack, Wiles made the decision to euthanize Ranger, who suffered a severe chest wound.

The other dog will now be required to be on a leash at all times while at dog parks, per a Johnson County ordinance. Park police say the dog's owner has been cooperative.

Wiles said his family would like to see changes to county dog parks moving forward, including cameras at all parks, a separate area for small dogs and a requirement that all dogs are up-to-date on shots.
