The FDA says some flea and tick medications may be causing dogs and cats to have seizures. 

A chemical found in many popular brands of flea and tick medications is reported to cause neurological problems in pets.

A veterinarian spoke with CBS 58 News and says these issues are very rare but some pets may be more at risk than others.

"We have to believe that these dogs have a sensitivity to the product or they might have an underlying issue that's brought on by use of the product or it could be totally coincidental also," said Pete Gaveras, a Veterinarian with the Silver Spring Animal Wellness Center.

The brands included in the FDA warning are Nexgard, Bravecto, Credelio, and Simparica.

Experts say you should consult your veterinarian to learn more about how these products may affect your dog or cat.
