here in Maine the dog food trick does not work well unless you can get in an area that is away from other baits. We use bakery items and caramel for our sites and we refill them every day. If a bear around here cannot get a good amount of food in short order then they will just find another bait site where the food is easy to get. One of our sites has five bear that show up regularly. We are pretty sure that these bear are all living within 500 yards of the bait site.
Last Wednesday we videoed 5 bear in the last hour of daylight with no shot(long story) and last night my daughter finally shot her first bear which we hopefully can recover today.
