Vinegar is like sour juice, but it's not good for dogs because it can make their tummies hurt.
Even though some people use vinegar to feel better, it doesn't help dogs the same way.
Vinegar can also irritate their mouths and make them not want to drink water, which is really important for their health.
Some vinegars have a little bit of alcohol, which is bad for dogs, so it's best to keep vinegar away from them.
