OK, no matter how bad the bugs are and no matter how annoyed and irritated your Brittany is, there is no excuse for using human bug spray on your dog. Some vets may recommend a simple strength human insect spray; however, make sure you only use what the vet says to and do not apply more than the instructions say. The main reason to stay away from using human insect or bug spray on your Brittany is because of the main ingredient known as DEET. This is a common item found in insect repellent for people and it can be very lethal to animals including your dog. If your Brittany gets bug spray on him or is standing to close when bug spray is applied to people, call your vet. Signs of poisoning may include drooling, seizures, vomiting and loss of appetite.
