Stop Person Spreading Thumbtacks at Dog Park

Dog Park_By_Don Graham

Target: Bill Goswick, Police Chief of Hercules, California

Goal: Install security cameras at local dog park to catch person spreading thumbtacks in and around park.

Someone has been spreading thumbtacks across the ground and in water bowls at the Ohlone Dog Park in Hercules, California. These sharp objects pose a risk to all dogs who might use this park, and at least two dogs have already been injured. Though volunteers have cleaned up the thumbtacks multiple times, the person or persons responsible continue to return and spread more thumbtacks. Whoever is spreading these dangerous items is obviously intent on harming local dogs, and it is time for the police to install security cameras at the park in order to catch the person responsible.

Community dog parks are supposed to be safe spaces for dogs to have the freedom to run and play. Intentionally placing sharp objects around a park is mean and cruel as these objects can cause serious pain and injury to the sensitive paws of dogs. It is estimated that dog owners picked up between 3,000 and 5,000 thumbtacks in one day at Ohlone Dog Park. Not only is this person spreading thousands of thumbtacks across the park, but they continue to return and spread more tacks once the others have been cleaned up. It is apparent that the perpetrator is intent upon hurting dogs and threatening their safe space.

This battle to keep the Ohlone Dog Park clean and safe has been going on for weeks, and it’s time for more dedicated efforts to be taken. In order to catch whoever is responsible, the local police need to do more than simply patrol the area — it is time to install a security camera. Please sign the below petition to show your support for the health and safety of dogs in Hercules by demanding the local police install a security camera in order to catch whoever is responsible for this cruel act.


Dear Chief Goswick,

I am writing to request that you and your department install a security camera at the Ohlone Dog Park. Someone has been cruelly spreading thumbtacks around this park in an attempt to harm local dogs. Despite efforts to clean up the tacks, the perpetrator continues to return and spread new ones. It is apparent that whoever is spreading these tacks has yet to be deterred, and it is time for more serious measures be taken to apprehend them.

The safety of community dog parks is essential for the health and happiness of local citizens and their animal family members. As of now, at least two dogs have already been injured due to the spreading of thumbtacks in Ohlone Dog Park. The intentional placement of sharp objects within the park is mean and cruel, and whoever is responsible must be stopped as they are willfully threatening the safety of your community.

I know that your department has already taken measures to try and apprehend the person or persons responsible for spreading these tacks. However, this continued risk to the health and safety of your local dog population is not to be tolerated, and it is time for more serious action to be taken. Please support your local pet community by installing a security camera at Ohlone Dog Park so that whoever is committing this cruel act can be caught and punished.

  1. death to the punk or punks that are putting thumbtacks at the dog park now.

  2. Barbara Chichester says:

    I wish I lived in California, because I would be watching for this individual or individuals all hours of the night and day, and I would catch them and turn them in.

    Because if you can do this to an innocent animal, you can do this to a human.

    Punishment should be picking them up in mouth, one by one.
