Product Reviews

  1. Great results

    Posted by Randy W. on Nov 6th 2014

    The Sportdog Field Trainer might seem like a hunting dog trainer but it is really for a family dog too. We have been using the collar for about a month and our dog has done amazing. We no longer have to worry about her running off. She is able to be off leash and most situations and she gets better at listening every day. This collar has made our dog a much better behaved dog.

    It worked great for a very stubborn German Shepherd.
