Hi.. I moved into my dream unit here on the Sunshine Coast, Qld with me furbaby Rico..After my first day at work (I work a split shift 5-8.30am and again at 2.30-6pm weekdays), I received an email from the real estate, saying a NEIGHBOUR had complained about Rico crying when I was at work...I became extremely anxious every time I went to work...I decided to seek an answer...so I started researching anti-bark collars... Decided to try your small dog collar....PROBLEM WAS SOLVED FROM DAY 1.....I couldn't believe it....NO COMPLAINTS since...Success was immediate....I am sooo relieved and greatful..it was worth every cent...Thankyou from Tammy and Rico 🐶👍
