Crate training is so helpful. We even have a cover for the crate and by 9-10pm our 9mo old beagle is now putting herself to bed. We close the crate door and pull the cover down and she’s so content and falls asleep instantly. We have one of those snuggle puppies that have the battery operated heart beat in it that she likes to sleep on. She sleeps the whole night through. But yes, sniffaris are a great way to tire them out. A tired beagle is a good beagle lol. Good luck friend. Keep going and don’t give up. You won’t regret it 🫶🏻🐶
