Laundry detergents
Fabric softeners contain cationic detergents which are very harmful to dogs, according to the ASPCA. Moreover, some laundry detergents contain enzymes to loosen stains and dirt. Cationic detergents are the most toxic if ingested. Harmful effects of these detergents include drooling, vomiting, oral and esophageal ulcers and fever. They can even kill your pet if swallowed, so try to keep your beloved furry friend away from these chemicals.
