Can Dogs Eat Tomato Sauce? No — Garlic and Onion Make It Toxic

Warning Signs & Symptoms

Garlic and onion: hemolytic anemia. High sodium: sodium poisoning. Spices: digestive upset.

If Your Dog Ate This

all commercial tomato sauce — garlic and onion content

Preparation & Serving

Never feed tomato sauce to dogs. Make plain mashed tomato separately if desired.

Safer Alternatives

  • Plain ripe tomato flesh as a safe alternative

Did you know?

Store-bought tomato sauce lists garlic as one of its primary flavor ingredients — and because the sauce is cooked and reduced the garlic becomes more concentrated than the equivalent amount of raw garlic.
