Both breeds have similar behaviours, but I have never seen a lazier dog than a Basset Hound! My mother has one, and it was always a lazy dog. Even a small wall was similar to torture to him. When I started to live alone, I bought myself a French Bulldog, and it is way more active than a German Shepherd. The only thing I was struggling with was his nutrition. It is allergic to a lot of things. Luckily I found a nutrition plan on ourfrenchie.com, and I never had any problems feeding my dog by following it.
