I need some advice on purchasing or adopting a Basset Hound. My children are both very hyper and outgoing, so I adopted them a beagle/weiner dog mix from the Humane Society, he fits great with their energy level. I would like a more laid back and gentle dog for myself. I have been doing research on Bassets. Has anyone ever had any experiences with an agressive one? Or are all of them pretty mellow and sweet? There is a Basset Hound rescue group about 2 hours from where I live, this may be the way to go. Someone on this site posted that a dog's personality isn't fully developed until they are a year old, but what if they have been abused or abandoned, what then? The rescue doesn't take in puppies usually, only older ones. How do I know if their past will affect their personality now? Any advice would help.
