When it comes to flea shampoo, it’s important to understand that not all flea shampoos are created equal. While cat flea shampoo might seem like a quick solution to use on your dog, it’s important to consider the ingredients in the shampoo and whether they are safe for your furry friend.

Cat flea shampoos often contain pyrethrins, which are insecticides that can be harmful to dogs if used in excess. Dogs are more sensitive to pyrethrins than cats, meaning that cat flea shampoo could potentially cause harm to your dog’s nervous system if used improperly.
