Snow, ice and cold temperatures affect dogs every winter season. Exposure to extreme cold temperatures can put pets in danger of serious illness. Dogs who have diabetes, kidney disease and heart disease lack the ability to regulate their own body heat. Providing dogs with a soft and warm coat during the cold season is part of a pet owners winter routine.

Create a Pattern

Step 1

Take measurements of the dog's chest, neck and back area. Measure from the base of the neck to the base of the tail. Next, measure around the dog's neck in a complete circle, add 1 inch for comfort. The width of the band around the neck should be at least 3 inches, depending on the size of the dog; add or subtract from the 3 inches when necessary. The width will protect the dog's neck area from the cold weather. Then measure the lower chest area, starting from the side of the tummy and reaching to the other side, directly in comparison. Add an extra 4 inches to one side. This is where the coat will adhere in place.

Step 2

Mark the dog's measurements onto the pattern paper. First create the pattern shape for the neck area. Use a ruler to draw a rectangle using the measurements that were taken around the dog's neck. Next create the chest flap. Draw a rectangle shape using the measurements taken around the dog's belly. Then create the pattern for the back area. Divide the measurement for the back, that was from the base of the neck to the base of the tail, divide it in half. Use a ruler to draw a straight line, this will be the length of the coat. Then draw a half circle below the base of the neck, right above the dog's leg area. Draw a straight line down from the half circle, meeting the same length as the first line drawn for the base of the neck and base of the tail measurement. Then use the ruler to draw a straight line across the bottom to meet the two lines. Also draw a straight line across the top near the neck area to meet the two lines. The pattern should look like the shape of a rectangle, with a half circle cut out right below the top left corner edge of the pattern.

Step 3

Place the pattern on top of the polar fleece fabric. Pin the fabric to the pattern. Carefully cut the fabric using the pattern as the guideline.

Sew the Coat

Step 1

Machine stitch the back panel to the fabric that is for the neck area. Sew a straight line using the pins as a guide.

Step 2

Sew the chest piece that is pinned to the garment. All three pieces should be attached together, with the exception of the loose chest piece that is only attached on one side of the garment.

Step 3

Cut a 2-inch square piece of Velcro. Increase the size of the Velcro for large breed dogs. Sew the bristle part of the 2-inch square Velcro piece to the closest edge of the loose part of the chest flap. Then sew the fuzzy piece of the Velcro to the side of the coat, in a location where the chest flap can adhere to the Velcro piece easily and provide a snug fit to the dog's body. This is where the coat will attach and detach.


  • Tight fitting coats around the dogs neck area can cause breathing difficulties.

  • Remove the coat when indoors to prevent overheating.
