Except as provided for in subparagraph (B) of paragraph (6) of subdivision (b) of Section 122140, no pet dealer shall knowingly sell a dog that is diseased, ill, or has a condition, any one of which requires hospitalization or surgical procedures. In lieu of the civil penalties imposed pursuant to Section 122150, any pet dealer who violates this section shall be subject to a civil penalty of up to one thousand dollars ($1,000), or shall be prohibited from selling dogs at retail for up to 30 days, or both. If there is a second offense, the pet dealer shall be subject to a civil penalty of up to two thousand five hundred dollars ($2,500), or a prohibition from selling dogs at retail for up to 90 days, or both. For a third offense, the pet dealer shall be subject to a civil penalty of up to five thousand dollars ($5,000) or a prohibition from selling dogs at retail for up to six months, or both. For a fourth and subsequent offense, the pet dealer shall be subject to a civil penalty of up to ten thousand dollars ($10,000) or a prohibition from selling dogs at retail for up to one year, or both. For purposes of this section, a violation that occurred over five years prior to the most recent violation shall not be considered. An action for recovery of the civil penalty and for a court order enjoining the pet dealer from engaging in the business of selling dogs at retail for the period set forth in this section, may be prosecuted by the district attorney for the county where the violation occurred, or the city attorney for the city where the violation occurred, in the appropriate court.
