My Dog Was Laid to Rest on 7/7/18

I'm uncertain how to apply numerology calculations to a dog. My practice is focused on people.

But dates do have numerology meanings, which is an interpretation of the energy a date represents. Perhaps the date's meaning can help you determine significance.

The number 7 is a number of introspection. Also of spirituality and wisdom. And other things that you'll find at the linked article.

Because the number 7 is both the number of the month and the number of the day, the energy the number 7 represents is likely to be much stronger in respect to the date.

In numerology, the year number for calculations is 4 digits, not the commonly-expressed 2-digit version.

The number 2018 is a number of relationships, companionship, and diplomacy. The link will tell you more about the number.

The energy represented by the date, then, is heavily composed of introspection, spirituality, and relationships.

I hope that helps you find significance and reason.
