Can dogs eat vinegar, and why?
Vinegar is very acidic and best avoided; only highly diluted use is sometimes suggested. The acidity can cause stomach upset, especially in small dogs or sensitive tummies.
Dogs are omnivores, so most of their diet should be a complete, balanced dog food, with treats on top. They cope with a wide range of foods, but rich, fatty or sugary ones can cause stomach upset and, over time, weight gain or pancreatitis.
Warning — what to watch for
The acidity can cause stomach upset, especially in small dogs or sensitive tummies.
