Thank you for viewing. I believe it's clean without any stains, but as it's a personal inspection, please forgive any oversights. Please refrain from purchasing if you are concerned about minor details. Thank you for your understanding as this is a used item. To prevent any issues, please ask any questions in the comments section. This is a functional garment with warm boa and terahertz fabric on the chest. Terahertz is especially recommended for dogs that are weak, prone to illness, or senior dogs. Of course, healthy dogs can also wear it to maintain their health!
