The Short Answer

Acrylic suits most dog sweater ranges. It is warm, light, easy to wash and holds color well. Cotton suits mild climates and buyers who want natural fibers.

Many brands stock both. They use acrylic for winter and holiday styles and cotton for spring and autumn.

When to Choose Acrylic

Choose acrylic for cold-weather and holiday styles. It gives bright colors for jacquard and Fair Isle patterns. Owners can wash it often without much care.

Acrylic is also the easier choice for a first range. Most stock styles use it, so you can start small. In-stock orders start at 2 pcs per style and 50 pcs per order.

When to Choose Cotton

Choose cotton for light layers and mild weather. It suits dogs that run warm and owners who prefer natural fibers. It works well for spring and autumn ranges.

Cotton needs a clear care label. Tell customers to wash it cool and dry it flat.

Acrylic and Cotton Blends

Blends mix the two. An acrylic and cotton blend keeps some of the softness of cotton with easier care. Ask for the fiber content in percentages for each style.

Ordering Either Yarn

Check the material on each card in the in-stock range. For a style in a different yarn, place a custom order from 100 pcs per style and color. Read the yarn guide for wool and novelty yarns.
