You need a photograph that is
So use a pose that is typical of your pet, so your dog is relaxed and chilled out. The photo below is an example of the images that are best to work with. To achieve this the following guide helps you take a great photo.
The best possible lighting is achieved outside in real sunlight or by a window. If you are outside and if the sun is out, have the light source behind you. But avoid direct sunlight shining into the eyes of your animal, as this will make your pet squint and also you may get dark shadows on the face and the colouring of the fur will not be true.
The best day is a bright overcast day (not too heavy cloud so the light is still getting through though). Even on an overcast day, make sure the light source is behind you. We can't see it with our eyes, but the camera does and if your pet has his or her back to the sunlight there will still be shadows. Check where the sun would be if it were out and then stand with your back to it.
If you have to take your photo indoors, then in a light room near the window is best. Morning light is best, as it is bright and crisp, try it with your back to the window and your pet facing the window. Try to avoid using the flash, as this will cause red eye in your photo, although this can be fixed by us later!
The best position of your pet is to have yourself right down at the same level of your pet. Photos pointing down don't look right. If need be, lay down on the soil, get down and dirty!
It can sometimes be a good idea to have someone next to you with a favourite toy or sweetie, or to say a word that gets your pet to look interested. Have your pet look at the person next to you. As this pose is better than staring straight at you or completely side view. A slight angle to the side is much better, so you can see both eyes, take a look at the photo in this description.
If your pet is small enough, it works well if someone holds them in their arms. Don't worry we can leave the person out!! It's a good idea to get several photos over a period of a couple of days. We don't want your pet to look fed up!!
And finally remember to have fun, if you start taking photos well before you need the painting then there is no rush or stress on you.
