These adorable lavender and black polka dotted jammies have more coverage under the belly to assist with pets that may have allergies or post surgical healings and tend to scratch and chew the belly/chest area. Therefore, your pet will have to show a little more patience as you work their front legs into the leg holes. Naturally with the extra belly coverage, the open rear area is smaller where your baby will need to do her/his business. (See next to last picture) The jammies are also lined with a soft, white lining.  Returns accepted in good condition. Buyer pays return shipping. Ships to USA only.*Note Sizing: Should generally accommodate a pup with length of back (from base of neck down the back to tail) of 12-14"; neck size of 10-12"; chest circumference of 16-18" MAX. Please measure your pet as sizes are not the same everywhere, depending on the manufacturer. DON'T GO BY LABEL SIZE ALONE.**With measuring tape, measure the length from the base of the neck down the back to the tail; measure around the neck where the collar lays; measure around the largest part of the chest, usually just behind the front legs. ***See last picture as example.
