1.If between sizes, please size up.

2.Our clothes are NOT suitable for large breeds of dogs.

3.Always choose sizes according to the latest measurement of your pet.

4.Your baby usually wears size S doesn't mean all size S will fit him/her. Different designers and manufacturers use their own size charts.

5.If your pet is under one year old and still growing, please take this into consideration.


Please always choosing the size by the measurement of your pet (The chest girth and back length), not the weight or breeds simply. Your carefully choice will avoid plenty of inconvenience of returns.
