### Causes, Symptoms, and Treatments for Excessive Drooling in Dogs **Breeding:** Some breeds like Bloodhounds, Newfoundlands, mastiffs, and Saint Bernards have loose upper lips that cause them to drool more. Keep a hand towel or bib handy. **Mouth Disease and Tooth Decay:** Tarter buildup can irritate your dog's lips, causing drool. Check for brown teeth or red, swollen gums. Professional cleaning and daily brushing can help. Vets can also check for gingivitis, mouth ulcers, and tumors. **Heat Stroke:** Breeds like pugs and bulldogs are prone to heat stroke and drooling. Ensure they have fresh water and shade. Keep them indoors on hot days and never leave them in a parked car. Contact your vet immediately if you suspect heat stroke. **Motion Sickness and Anxiety:** Car rides can make dogs anxious or nauseated, causing drooling. Use a pet harness and gradually get them used to car rides. Consult your vet for remedies or medication if needed. **Organ Disease:** Liver and kidney diseases can cause drooling, especially in older dogs. Annual checkups are recommended for early diagnosis and treatment. **Poisonous Plants or Animals:** Plants like tulips and azaleas, or animals like certain frogs and spiders, can make your dog drool and feel sick. Prevent your dog from eating them and consult the ASPCA for a list of poisonous plants. **Stomach Aches:** Dogs often eat things they shouldn't, causing nausea and pain. Keep dangerous items away and call your vet if you suspect your dog has ingested something harmful. **Upper Respiratory Infections:** Infections of the nose, throat, or sinuses can cause drooling. Dogs in homes or shelters with other pets are at higher risk. Keep your dog indoors and away from other pets, and wash your hands between handling different animals. If your dog acts strange for more than a day, seems stressed, vomits, or isn't eating or playing as usual, see a vet.
