More than 10 states have some form of protection for pets from implantable microchips, according to the nonprofit Pet Owners Coalition.
The coalition says these laws are a step toward addressing a growing problem of pets being implanted with devices that could potentially harm their health.
The group released a report Tuesday calling for more state legislation to protect pets from these types of implants.
In states where they exist, they are often used to detect diseases like cancer and heart disease.
They can also help in detecting tumors or cancer cells.
In the report, the Pet Owners Committee said pets should be protected from these implants because they can cause cancer.
“The vast majority of pets, if not all, do not need the microchip technology to identify and protect themselves from disease and to help them fight disease,” said the Pet Owner Committee in a statement.
However, the report notes that pets can have problems with microchipping.
For example, dogs and cats may not be fully vaccinated against the virus that causes microchipped animals to be less able to fight off infections.
It also notes that dogs and other pets that are infected with coronavirus may have a more difficult time controlling their infection if their owners are not vaccinated.
Pet owners are also concerned about the implants, and the Pet Insurance Association said it was investigating pet insurance policies that did not cover them.
The association added it was also exploring the possibility of requiring owners to get a chip card from their pet.
Other states that have protections for pets against microchip implants include Oregon, Connecticut, Indiana, Illinois, New Jersey, Ohio, Rhode Island, Virginia and Wisconsin.
