I am very happy with the service and the products I purchased a barking collar for my small dog and it works a treat and the invisible fence for my larger dogs who have been escaping for years and not once have they got out since we put the fence up???? we rang up dog line for advise on how to set up fence and they were very patient with us and explained everything the services at Dog Line is brilliant and so are the products I tell everyone about them and I work in a pet shop so I have had experience with similar products but nothing even compares to dog line I would like to say Thankyou for saving my pets from lots of trouble from council and neighbours no more escaping and no more barking yay everyone is happy ????????
