Hi Scott. I like #15! My exeutive board many have a concern that it is not visually "bulky" enough. (Does that make sense in designer-speak?) We looked at some logos earlier in the year that we liked but they kind of disappeared when they were downsized...looked fine normal size. Also with the fonts, if you could use gold for the "Golden Retirever" and green for the rest of the organization's name that would be great.
Those are my comments. Great job!
