I've moved your post to the Photography section and if you look at the top of this board there's a couple of great stickys by Nicola with hints for taking good photos of dogs - not so easy for us mere mortals to put into practice though, I know.
From your avatar it looks like Poppy is solid black Cocker, the hardest to photograph (one of mine is a dark blue roan so I sympathise) - outside in daylight would probably be best, with her facing towards the light so her eyes can be seen properly... also teaching her a good 'sit and wait' ( using treats) so you have time to take the shot.
