This is very sad friend. Did he find a home? If yes, did you get details. You cannot control a hound dogs desire to hunt too many smell receptors, a believe beagles have 250 million smell receptors to our 250,000. There smell is stronger than their will. A hound dog does not smell a hamburger, he smells bread, beef, lettuce, ketchup, mustard. Cheers to you for doing the right thing; as rough as it was.......
I purchased a beagle for my daughters 16. I failed to do research on beagles before we got one and I had NO IDEA what I got myself into for 15 YEARS. At least we have 5 acres and I went through blood to get a wire buried covering the entire 5 acres. ALL DAY EVERY DAY she howls. All this said, I love the dog.
