How does the American coat type often differ from the original Irish coat type?

The American variety is often described as thicker and fuller, sometimes appearing "bouffant," and may require more grooming attention.

Breeders recognize two primary variations in coat presentation based on geographical preference or standard adherence: the Irish and the American coat types. The coat favored by those adhering to the original Irish standard is characterized by being silkier in texture, having a wavier appearance, and lying closer to the dog's body. This texture is also associated with being slightly oilier and potentially less prone to tangling because of its water-resistant nature. Conversely, the American coat type is frequently described as having more volume—thicker and fuller—often leading to a 'bouffant' look, which consequently tends to grow faster and necessitates a higher degree of grooming attention from the owner to maintain manageability.
