What's the best dog collar/dog brand?

If you're looking for a tracker to add onto the collar, I would recommend the Findster Duo. It uses bluetooth to connect to a small device you keep in your pocket, meaning there's no monthly fees like other trackers. It's been really accurate for me and it's super easy to setup.

One of my friends just started working there. Their products help you keep tabs on your pet’s location and activity levels.
