Vinegar
CautionHousehold vinegar is 4-7% acetic acid, so undiluted licks irritate the mouth and stomach. Cooking amounts are usually a non-event. Skip the apple cider vinegar in the water bowl, and treat 30% cleaning vinegar as a chemical burn emergency.

More about this food
Table vinegar is an acid solution, typically 4-7% acetic acid. The amount cooked into a salad dressing, a marinade or a pot of pickles is usually a non-event for a dog. Problems start with the undiluted liquid. Acid contacting the mouth, esophagus and stomach lining causes drooling, gagging and vomiting, and a dog with existing gastritis, ulcers or reflux reacts harder. If a dog knocks over a bottle and gulps at it, some can be aspirated, which brings coughing and labored breathing.
Apple cider vinegar in the water bowl is a popular home remedy and not a good idea. No benefit for joints, itching or fleas has been established in dogs, and the Merck Veterinary Manual states plainly that nutritional supplements are not required for a dog on a complete and balanced diet and may be harmful in some cases. The practical harm is simpler than toxicity: sour water means a dog drinks less, and a dog that drinks less gets dehydrated. That matters most in exactly the dogs whose owners try the remedy -- seniors, and dogs managed for kidney or urinary disease.
There is one use to rule out completely. Never use vinegar, salt water or mustard water to make a dog vomit after it eats something. With a corrosive or a petroleum-based product, bringing it back up burns the esophagus a second time, and aspiration is a real risk. VCA's essential oil poisoning guidance says it directly: do not induce vomiting or give activated charcoal at home. Whether to decontaminate is a decision for your veterinarian or the ASPCA Animal Poison Control Center at (888) 426-4435.
Cleaning vinegar and horticultural vinegar are a separate category. At 20-45% acetic acid they are corrosive, not culinary, and a lick or a spill on the coat is an urgent problem. Rinse the mouth and skin with plenty of lukewarm water, do not induce vomiting, offer a little water to drink, and go in. For an ordinary splash of table vinegar, rinse the mouth, let your dog drink freely and watch. Call if vomiting repeats, if drooling does not stop, or if swallowing looks painful.
Frequently asked questions
- My dog licked salad dressing off a plate. Is vinegar the problem?
- Rarely. The vinegar in dressing is dilute and mostly harmless in that amount. Look at the oil, the salt and, on many labels, the onion or garlic powder instead, and call your vet if vomiting or diarrhea keeps going.
- Should I add apple cider vinegar to my dog's water?
- No. Nothing in dogs supports the claimed benefits, and Merck notes that supplements are unnecessary and can be harmful for a dog eating a complete diet. The realistic downside is that sour water reduces drinking, which is the last thing an older or kidney-compromised dog needs.
- Can I use vinegar to make my dog throw up?
- Never. Home emetics can burn the esophagus on the way back up and can be aspirated into the lungs. Call your veterinarian or the APCC at (888) 426-4435 and let them decide whether vomiting should be induced and how.
