Highly recommend dogline, I wasn't sure what to get so went on to chat and told them my problem, I recieved excellent service and advice on what to get so I ordered the product and even though I live remote I recieved it in 2 days. My dog is usually very obedient untill she gets too excited for something and she just won't come when I call, after following instructions of how to use the sportshunter she has learnt very quickly and it has helped so much with her training it is amazing. I no longer have to have her tied up in the car out in the bush, no more worring she will run off chasing something and get lost.
