Plans to scrap stringent rabies safeguards prompted horror in Portsmouth.
Experts warned that proposals by MPs could trigger the return of the disease, which killed half of those it infected.
A report from the select committee of agriculture was said to be in favour of ending the six-month quarantine rules and bringing in a vaccination scheme and a pet passport.
Britain had been rabies-free since 1922 and quarantine was a tried and tested method that kept it that way, said Portsmouth south MP David Martin.
The report was said to recommend animals also have a microchip tag inserted in the scruff of their necks which could be checked by scanners.
