sensitive dog trainer is looking for a logo design

This short briefing was written by a client:

target-audience

About me: Dog trainer, Dog walker, behaviour therapist
target group: dog owners, who like to understand their dog and like to develop a non-violent relationship, affected by love, trust, tolerance and respect.
My ambition: self-confident dog owners who know that only a self-confident dog could be a reliable dog in our society.

Description

The design should be young and fresh, but for all that also trustworthy. Clear lines as possible, not too much of enrichments. I prefer warm colours like brown etc (dark green is also possible and secure in the www) or black because my website is written dark brown in a nude-coloured box. The background is a photo of a dog/nature.
I am myself not sure if I like only the initials (sd), the name with symbol or the name with a figure.
In the attachment you can find some suggestions of me. But it could be also something else. Feel free to improve one of my ideas or create something else! Your unlimited ideas are welcome... :-)
