The electronic pet fence industry began in 1976 when John Purtell founded the Invisible Fence brand. He and his team managed the company’s incredible growth for seventeen years. You’ll find this history on Wikipedia.

After selling the company at its zenith and waiting out a non-compete, John Purtell joined Perimeter Technologies and attracted several former Invisible Fence employees. Together they redesigned the Pet Stop product and grew a different type of professional dealer network.

Unfortunately, the Invisible Fence® website displays an untruthful history of Invisible Fence by removing any mention of John Purtell and his history developing the Invisible Fence brand. The attempt to try to revise history may be understandable given our competitive positions, but to deliberately post an untruthful history causes one to question the integrity of this company.

Regardless, we are proud of John Purtell’s vast accomplishments within the electronic pet fence industry, which he started many years ago with Invisible Fence. Most notably, the Pet Stop brand benefited enormously from John Purtell and his former staff in creating unique technology sold by dealers who are experts in their craft.
