I used a bell in the first two seasons. It kept falling off as she would go into thick brush. Sometimes she amazed even me, slipping thru such stuff which looked like a cantalope wouldn't fit. Anyway, I keep going to store to buy another bell for her. I finally got disgusted and gave up.

Sproulman, if you're having trouble with other hunters, I would try the vest. (And perhaps some inflatable balloons tied to her collar, you know those cellophane ones? )
