I don't have this model but I do have an older Nikon DSLR and I absolutely love it.
My advice is to read Nicola's articles about photographing dogs and do try the other settings.
You may feel more comfortable using the auto mode to begin with, but after the first day I was experimenting with the different modes and luckily with digital, it doesn't cost anything.
Have a great time with your camera and take lots of photos, you may have to delete loads to begin with but that doesn't matter as when you get that 'great' one, it will be worth it.
Look forward to seeing your efforts on the forum.
