I require a professional design and have attached some ideas although I'm not limited to these. I maybe thought of some emphasis on the unique spelling of the word 'Dogz'  as this will be the branding. ........I quite like the design to the bottom left of the page (the square one) however then I thought maybe use a 'circle' design to illustrate 'world' or 'globe.' ??.................................................I then found an image on Vector Stock of a German Shepherd dog with a circle around it (attached) which I thought was good.
