8. Skip the Bug Spray
Unless specifically designed for animals, insect repellent and sunscreen can be toxic to dogs. Be aware of the signs of toxic ingestion (provided by the ASPCA): drooling, vomiting, diarrhea, excessive thirst, and lethargy. DEET, a common insecticide, may also cause neurological problems in dogs. If you’re spraying, do it far from your dog.
