Shih Tzus often need a slightly different fit check from short coated dogs. Their fluffy coats can make a layer feel tighter than the size chart suggests, so measure your dog when the coat is sitting naturally and allow room for movement.
Start with back length from the base of the neck to the start of the tail. Then check chest room, especially if your Shih Tzu has a fuller coat or wears a harness on walks. If your dog sits between two sizes, choose the size that gives comfortable chest room rather than a neat photo fit.
Best Lucky Pup layers for Shih Tzus
For light everyday wear, start with the raglan dog T shirt. It is a simple first layer for dry walks, garden time and family photos.
For cooler mornings, compare the dog hoodie with the warmer jacket styles in the Lucky Pup dog clothing collection. A hoodie gives a cosy casual layer, while a puffer or parka is better when your dog needs more warmth.
If your Shih Tzu has a longer coat, check that the arm openings sit comfortably and that the fabric does not pull when your dog walks, sits or curls up. The best dog clothes should help your pup feel comfortable, not just look cute for a photo.
