Introduction to Halo Collar 4
In this Halo Collar 4 review, one of the first things that stands out is the collar’s impressive versatility. Designed to accommodate dogs of all sizes, it features a fully adjustable fit and rugged, pet-safe construction built for everyday wear. Whether you have a small, energetic terrier or a large, adventurous retriever, the Halo Collar 4 adapts comfortably. The newest version also introduces key improvements – including a battery life that exceeds 30 hours and enhanced waterproofing, ensuring it performs reliably in rain, mud, or snow. To unlock features like real-time GPS tracking, virtual fence creation, and cellular connectivity, a subscription plan is required, starting at just $9.99 per month.
We’ve personally tested the Halo Collar 4 for over 60 days with our high-energy pup who previously loved bolting out of the yard. While the upfront cost and monthly subscription gave us pause, the collar proved itself within the first week. Setup through the app was intuitive, it walked us through fence creation, sound/vibration cue testing, and how to reinforce recall.
At first, we used sound only when our dog approached the virtual boundary. He responded well after just a couple of sessions. Over time, we added vibration for reinforcement, which significantly reduced the need to shout commands or run after him. The real-time GPS tracking gave us peace of mind, especially the first time he breached the zone and we located him within seconds.
Transitioning indoors, the Bluetooth and Wi-Fi tracking wasn’t perfect but was far more accurate than previous versions. We especially appreciated the activity monitoring, which helped us understand when our pup was under-exercised (usually leading to bad behavior later in the day).
