I am in need of an E-collar for my 11 mo old black lab. She is a great dog but forgets I exist when she gets distracted. Knows her commands and what she is supposed to do but very hard headed. Strictly a duck dog that also goes to work around logging jobs with me. She will wear it hunting/training primarily but will also use when around logging jobs. What is the best out there for the money these days? I don't want to spend more than $250 for it unless I have to but don't need the top professional unit. Being able to add a second collar to use on my gsp is a plus but not a necessity.
