Martha doesn't generally wear clothes, but she sometimes has.
- Her collar. Generally, the only thing worn by her.
- A costume of a pet door. Worn to the birthday party of Alice Boxwood.
- Three pink ribbons. Worn to the dog show.
- A pink poodle suit (only in her dream)
- A red helmet with yellow markings, red anklets, navy blue leggings and a red necklace (again, only worn in her dream)
- Martha's cone
- A beige, red-trimmed shroud, purple veil, and straw hat with a blue ribbon-when disguised as an old lady in a wheelchair.
- A Courageous Collie Carlo collar-given up as it was too itchy.
