Coocouture Dog Recovery Wear Recovery Wan Terahertz One Back Opening Tank Pink [Although the official Coocouture website lists it as pink, it's a muted pink color, like a mix of pink and purple.] Back opening, snap button type. Please search for the effects of Terahertz yourself. I bought it to wear as an inner layer. It has a lot of stretch, but it was tight on a 4.5kg dog. It seems like it would be better for a lighter dog, with more room. ⚠️Please note⚠️ I will use a lint roller before sending it, but please refrain from purchasing if you are concerned about dog hair, odor, or the feeling of wear. Size: M Please refer to the measurements in the photos for detailed sizing. For reference, a 4.5kg Dachshund wore this. At the same time, the dog wore DS size from Pet Paradise and DM size from Full of Vigor. The dog gained weight and can no longer wear it. Shipping costs can be discounted if you purchase other items to be shipped together.
