In the few weeks I have been using the EZ900 Educator remote trainer, it had absolutely changed my life & that of my fur baby Archie! From the very beginning & even on the 1st day of activation Archie was quick to understand my commands, avoiding eating food found in the park & not reacting to a barking dog off lead. Walking the streets has again become enjoyable instead of intense & stressful. The remote has already taught my dog to avoid lashing out & barking at dogs walking past. In off leash areas the collar has already avoided him chasing people jogging, kids running & playing with toys , eating foreign found food & eating other dogs 💩 This system is awesome definitely ⭐️⭐️⭐️⭐️⭐️
