What matters most for small dogs

Small dogs need a GPS collar that does not weigh them down, so the tracker should be compact and the strap slim. A bulky unit unbalances a little dog and can rub, while a short adjustable strap stops excess length flapping around a small neck. Comfort and a secure, low-profile fit are the priorities here.

Even small dogs can slip a collar and vanish, so reliable alerts and a snug fit matter as much as on a big dog. Check that the buckle is easy for you to fasten yet holds firm, and that the strap shortens enough for a toy breed. A lightweight, water-resistant tracker copes with everyday adventures. Fit it with two fingers underneath so it cannot be backed out of, and watch that the weight does not make your small dog hunch or scratch at its neck.
