The dealer shall retain one copy of the certification provided under this paragraph for a period of at least one year for enforcement purposes.
Certification requirements may be modified to reflect technological advances in identification techniques, such as microchip technology, if the Secretary determines that adequate information such as described in this section, will be collected, transferred, and maintained through such technology.
Any dealer who violates this section more than one time shall be subject to a fine of $5,000 per dog or cat acquired or sold in violation of this section.
