Rocks are nature's pedestals. I don't have to build a platform if a rock is available. Sometimes rocks place a small dog up high enough for us to see the sky, or a rock can put a dog in a stream so we can capture him/her in the water.
In all cases, rocks are a great commodity in the photo industry, especially for us pet photographers.
We have many rocks in our area. On our property, we have a number of very large rock formations, some which are used by me for photos, and others that are used by the animals that reside with us as well as our grandkids. Many of our parks and walking areas, also have great rock outcroppings.
In the photo below, three smaller dogs are brought to my level on a rock in the woods, at a local park once again providing a resting moment to dogs that may be very active or overly happy. You can tell by the expressions on these three faces, they were ready to G.O. at a moments notice.
