Today through Sunday (Aug 8-12) we will be featuring all of our Dogtra Electronic Collars. With each purchase of a Dogtra Electonic Collar, you will receive a $20 discount on one of our 4 DVDs on using electronic collars. This video highlights two of Dogtra's newer products: the ARC Handsfree and the 1900S Handsfree, and explains some of the functions of each and the differences between the two.
