The designs shown here will be shipped within 2 days of your order. Select the necklace of your choice and then just tell me the length you need. You can measure your pet's neck, then add approximately 1/2 to 1 inch to have a great fit. If the necklace is a little too long or too short when you try it on, just return to me with the adjustment needed and it will be done one time for no charge. For longer than 9", email me the length information, and I will let you know the added charge, (usually about $3.00 for every 3 inches.)
