Love the product and the service, got our boy jasper (Labrador x border collie) at 8 weeks old just after we moved to the city and didn’t want him to get out, bought a cheap boundary line (not dog lines one) and he walked up to the line and it went off, he then proceeded to walk to his water bowl and submerged it in the water. Without hesitation he walked back to the line to find it no longer works and he can go where he likes. He is now 3 and we have moved back to the family farm where he has chased the sheep and cattle before. Being we were going to be living there we had to know he wasn’t going to chase them when we were at work. We bought the dog line and set that up but also needed a waterproof one as he loves to swim and have dams on the property. Was contacted by dog line staff and was reassured that it would stand up to the task and it sure has. Was super easy to find what we needed on the website, even when we later had to get another collar for his brother Axel for when he comes to stay. Highly recommend dog line and as an electrician who is often asked if I know of any good lines I straight away recommend dog line.
