Pregnant animals can be transported, provided they meet the vaccination requirements of Rabies, one DHPP, and a negative Heartworm test. The administration of a DHPP to a pregnant animal goes against veterinary best practices. The MDAR was asked if an exception can be made, and the answer was “no”. Of course, the decision to transport a pregnant animal needs to be weighed against the stress such transport and quarantine will cause.
Nursing moms and litters cannot be transported due to MGL chapter 129 section 39g. We received an opinion letter on this and it appears to be difficult to challenge. The only exception might be in an emergency situation such as a natural disaster with special dispensation from the MDAR.
