I know that McCalls, Butterick and Simplicity carry patterns for pet clothes. They are in the part of the catalog that has crafts. This weekend Joann's is having a pattern sale, don't remember which brand is on sale. Then next week, later in the week, they will have another brand on sale. You can look up the pattern company catalogs online and see what they have for pets. The patterns are rather expensive not to buy them on sale. Walmart does carry a couple of brands, I think Simplicity and McCalls, they sell for half price. Joann's will be on sale for $1.99, I think. You can also look Joann's up online and look at their fliers.
