from my experience with my beagle, she is fine all day while my boyfriend and i are at work, she is alone for 8 hours a day sometimes depending on his schedule and sadie just sleeps. we dont crate her, we leave her in our living room/sunroom, its pretty dogproof and has a door to kepe her in there, she does just fine all by herself.
however at first we had issues with seperation anxiety, she chewed our door and some baseboards all up, but we figured out what we were doing wrong and corrected it. we were making too big of a deal when we arrived home, we would run in and immediatly kiss and cuddle her and such, we quit that, started getting in the door, letting her out of the room, then ignoring her for 10 or so minutes while we did our thing, then slowly gave her more attention, she never chewed again! thank goodness!
i think beagles make awesome pets.
they are low maintence dogs, super friendly, they love everything, they are a "dog" - they can go hiking, some go swimming, etc. and they are just so full of expression, its amazing their expressions they have.
while they are incredibly smart, they are incredibly stubborn, somewhat difficult to housetrain, and have a tendancy to gain weight if not monitored closly and excercised enough.
i wouldnt trade my beagle for anything though, i love her mischeviness, i love her cute apologetic face. ill probably always have a beagle, or at least one hound in my house.
