I was very hesitant about using the collars as my furbaby is basically my child, after she escaped twice onto a busy main road I knew I had to do something and fast after speaking to the team, all I had to do was purchase a collar as we already owed the boundary line. Then when I spoke to Colin, I became more relaxed with the idea. So we installed last night and set everything up after receiving my furbabies "new surprise" collar yesterday and we are not even at 24 hours of use yet and I am seeing amazing results. The peace of mind this has bought me is fantastic and I'm extremely keen to purchase one for my daughters cat who is also a little escapee. Thankyou Dogline and especially Colin for all you guys have done to help keep my furbaby safe Regards Annette Smith.
