No dog is too old to be trained. You just have to be really consistent with her. If you let her get away with something once without re-directing her, she'll think it's ok to do and definitely will do it again.
Hey everyone!
My name is Jason. I have a 4 year old Dachshund named Freddy (and a 9 month old baby girl named Emily). I'm happy to be on dachshund-talk and look forward to interacting with everyone here!
