Your dog isn't just a good dog. He's the BEST. And it's all thanks to the outstanding training support provided by the Garmin PRO 70 Dog Collar. The simple, straightforward PRO 70 allows intuitive one-hand training and control with a range of one mile, so you don't have to take your eyes off your dog.

Pro 70 can expand to train up to 6 dogs (additional dog devices required) and features remote-operated LED beacon lights on the dog device for low light conditions and built in BarkLimiter, activated on the dog device, for a quieter kennel.
