This claim about a specific dog breed mix bringing luck or appearing only on "lucky days" is unverifiable. There is no scientific or empirical evidence that certain dog breeds or mixes can influence luck or appear only on specific days. The concept of luck is subjective and not measurable by any reliable method.

If you want to verify dog breed mixes, you can use DNA testing kits like Embark or Wisdom Panel, which provide detailed breed information based on genetic analysis.
