10. Rabies

While it’s unlikely that you’ll contract rabies from your pet (it’s most commonly contracted from wild animals like raccoons and bats), it’s within the realm of possibility since it is transmitted through the saliva of an infected animal. “The disease is most commonly contracted through a bite, although potentially it could be transmitted through a scratch as well,” says Gary Richter, MS, DVM, a veterinary health expert with Rover.com. “Although human exposure to rabies from a dog is uncommon, it’s worth noting since rabies is almost 100 percent fatal if the person is not treated immediately after exposure.” The best way to prevent it is to keep your pet up-to-date with their vaccines.

Symptoms in pets: Foaming at the mouth is the most common sign of rabies, but other symptoms could include behavioral changes, fever, hypersensitivity to touch, light, and sound, hiding in dark places, staggering, loss of appetite, and seizures.
