Groom Away the "Ickies" in Your Dog Photos
If you’re using Photoshop CS5 or later, choose the Spot Healing Brush from the Tools palette by right-clicking the Patch tool and then choosing the Spot Healing Brush tool.
If you’re using an older version of Photoshop, choose the Patch tool instead, because the Spot Healing Brush tool in older versions isn’t as smart, and you’ll probably have better luck with the Patch tool. If you use the Patch tool instead of the Spot Healing Brush tool, skip to Step 5. Again, if the Tools palette isn’t already visible, choose it from the Window menu in the Photoshop toolbar.
