#### how to get a dog paw print on paper

Press the paw immediately on paper, or the paint may run off or evaporate. If using acrylics, brush on a layer thick enough to capture the print; then press the paw onto the project surface. If space allows, create a large acrylic paw-print painting by dipping each paw into paint. Allow the dog to run across a large sheet of paper such as a roll of butcher paper unrolled across the yard. Wash
