As a dedicated pet parent, I’ve always been concerned about the safety of my beloved pup, especially when we’re out and about. That’s why I was drawn to the Halo Collar 4, a revolutionary GPS wireless dog fence that promises to keep my furry friend secure wherever we go.

The most accurate GPS feature of this collar is truly impressive. Despite living in an urban area with signal issues, I’ve found the dual-frequency GPS technology to be incredibly reliable. It combines L1 and L5 GPS bands, ensuring that my pup’s location remains unhindered by obstacles.

The versatility of this collar is another major selling point. Whether you have a small or large dog, the Halo Collar 4 caters to all sizes, with adjustable collars ranging from 8 inches to 30.5 inches. It’s also lightweight and designed for dogs weighing 10 pounds and up, making it an ideal choice for pets of various sizes.

Battery life is a crucial factor when it comes to pet technology, and the Halo Collar 4 excels in this area. With a battery life of 30 hours or more between charges, I can rest assured that my pup will always be connected.

Setting up the collar was a breeze, thanks to the easy-to-use app. The simple lessons guide you step-by-step, and live 11 help from customer service is available should you need it. Training my dog to respond to the Halo Fence’s boundaries has been a smooth process.

However, it’s important to note that a subscription is required for the GPS services and cellular data needed to create, edit, and use wireless dog fences. Pack Membership Plans start at $9.99 per month, which may be a consideration for some pet parents.
