I’d like to say that your logo and site are well balanced with the bulldog. I really liked that. What i see in the forum is either a different logo or a new logo. the bulldog was really good, and a lot of people have seen that bulldog. i would hesitate about changing your very well balanced site and brand too much… plus the bulldog is already branded in my mind, i bet others, too. switching to the rottie might be hard (a) switching the logo is never good for branding, (b) the rottie has a lot of details and is a harder logo to remember. the bulldog seems to indicate to me sturdy, thick, not going anywhere, and no bullshit.
aha’ probably more than you wanted to hear, but i figured what they heck, just opinions, and everyone has them :]
