You have already removed the padding for the day, why not do the same for the month?
	$ date +'%-d-%-m-%Y'
	7-1-2019

Here's a list of all padding modifiers from man date:
    By default, date pads numeric fields with zeroes. The following optional flags may follow '%':
    - (hyphen) do not pad the field
    _ (underscore) pad with spaces
    0 (zero) pad with zeros
    ^ use upper case if possible
    # use opposite case if possible
    After any flags comes an optional field width, as a decimal number; then an optional modifier, which is either E to use the locale's alternate representations if available, or O to use the locale's alternate numeric symbols if available.
