The Dog Line was so helpful when asking for advice to help us settle in our new puppy. We were nervous about leaving him for the first time when heading away and worried that he may bark the whole time for our dog sitter! After talking through options with us we went ahead and purchased a citronella bark collar from The Dog Line. It has worked a treat and we came home to a very happy and settled puppy! Thank you The Dog Line for your expertise and reassurance. We had a wonderful holiday as we weren't worried about Rocky although we did miss him terribly!. Here's a happy snap of him reunited with our 9 yo son Isaac.
