Someone removed a key picture (smart move). I know guys who run bear dogs, coon dogs, rabbits, and bird dogs (including duck retrievers). None would tolerate a dog that chase deer. Had a britany chase after a deer once. We finally got the dog back, owner told me to take off the dogs collar. Dog never ran deer after that day. Had it been my mutt I might have kept it around as a watch dog. Some people won't waste food on a dumb one.
