No—the HDE Halloween dog-pajama listing specifies 78% polyester and 22% cotton, not 100% cotton. If an all-cotton garment is your requirement, this listed blend does not meet it. That answer comes from the product description, not from how soft the photograph looks.
October costume shopping puts prints front and center; the NRF's September 22 seasonal survey includes pet costumes among planned purchases. Take one pause behind the pattern to check what the garment actually is.
Read the garment in three separate parts
The fiber statement: 78% polyester and 22% cotton identifies a polyester-cotton blend. It does not supply a tested warmth level, drying time or shrinkage rate. Nor does it establish that the outfit is suitable for every dog with a particular sensitivity.
The construction statement: the same listing specifies a pullover one-piece design with elastic ribbed cuffs. That tells you how the outfit is put on and how its edges are constructed. The description does not separately state a fiber composition for each cuff, so do not treat the overall blend as a detailed component-by-component label.
The fit statement: the product describes stretch construction and cut-out openings. Stretch is not a replacement for the chest, neck and back measurements in its chart. It also does not tell you a numerical stretch percentage or how much extra room to assume.
The shark print does not inherit the bat print’s blend
The separate Soft & Stretchy One-Piece Dog Pajamas listing describes soft, breathable stretch fabric and a Medium–XXX-Large range. Its current description does not give fiber percentages. It would be inaccurate to fill that gap with the Halloween garment's 78/22 numbers simply because both products are HDE one-piece pajamas.
If exact composition determines your purchase, ask for the material label for the selected everyday style and variant before ordering. A useful question is: “Can you confirm the fiber percentages for this exact print and size?” That is more precise than asking whether all dog pajamas are cotton.
For the Halloween pajamas, use the confirmed blend when making the decision, and follow the garment's actual care instructions rather than deriving a dryer setting from the percentages. For the everyday style, leave the unspecified composition unresolved until it is confirmed.
