Can Dogs and Cats Eat Apple Cider Vinegar?

Apple Cider Vinegar for Dogs

May help with skin health and digestion. Always dilute before use — never give undiluted. A teaspoon in water or food is sufficient. Avoid if dog has kidney disease.

The general rule of thumb is the 10% guideline — treats and extras should not exceed 10% of your dog's total daily calories. The remainder should come from a balanced commercial or vet-formulated diet. Introduce apple cider vinegar gradually, watching for any sign of digestive upset over the first 24–48 hours.

Portion guide by body weight

• Toy / small (under 5 kg / 11 lb): about a teaspoon, 2–3 times a week
• Medium (5–15 kg / 11–33 lb): about a tablespoon, a few times a week
• Large (15–30 kg / 33–66 lb): two to three tablespoons
• Giant (30 kg+): up to a quarter cup — an occasional treat, not a daily drink

Apple Cider Vinegar for Cats

Highly acidic and can cause GI irritation. Never give undiluted. Very small diluted amounts may be tolerated but there's little benefit for cats.

Because cats process many compounds differently from dogs, the safety threshold for apple cider vinegar can be much lower. Even a 'small taste' that a dog would handle may bother a cat. If you have any doubt, simply don't offer it.

How to Serve Apple Cider Vinegar Safely

1. Offer a small amount in a clean bowl — a splash, not a full serving.
2. Serve it plain and unsweetened, and never anything containing xylitol.
3. Give it at room temperature or slightly cool, never hot.
4. Refrigerate the rest and use it within 24 hours.

You can freeze it in an ice-cube tray for a hot-weather treat — offer one small cube at a time.

What to Avoid

• Sugar, syrup, or artificial sweeteners. Xylitol in particular is severely toxic to dogs and is hidden in sugar-free gum, peanut butter, baked goods, and even some toothpaste.
• Garlic and onion in any form. Both are toxic to dogs and cats, including powdered forms in sauces and seasoning mixes.
• Chocolate, coffee, or alcohol served alongside or mixed in.
• Salt and salty cured products. Pets can develop sodium ion poisoning from amounts that seem trivial to a human.
• Cooked bones if Apple Cider Vinegar is served with meat. Cooked bones splinter and can perforate the gut.

Signs of a Problem

Even with safe foods, individual sensitivities are real. Stop feeding and call your vet if you see any of:

• Vomiting or diarrhea, especially repeated episodes within a few hours
• Excessive drooling, lip-licking, or pacing
• Lethargy, weakness, or unwillingness to move
• Difficulty breathing, swelling around the face, or hives
• Tremors, twitching, or seizures — always an emergency

If your pet's symptoms are severe, contact an emergency veterinarian immediately. In the United States the ASPCA Animal Poison Control Center is reachable 24/7 at +1 (888) 426-4435.
