Can dogs eat fruit juice?

Caution — sugar and sometimes toxic fruits

Most fruit juices are too sugary for dogs. Grape juice is toxic (like grapes). Apple or orange juice in tiny amounts isn't dangerous but not useful.

The full picture

Fruit juice is essentially concentrated fruit sugar without the fibre — not dog-appropriate. Grape juice is flatly toxic (same reason as grapes). Orange, apple, and cranberry juice in small amounts aren't toxic but provide no benefit and a lot of sugar. Pineapple juice is similarly fine but pointless. Citrus juices (lemon, lime) are too acidic. Tomato juice often contains salt and spices. Pomegranate juice can cause stomach upset. The safe rule: water is what dogs need. Juice is neither helpful nor — except grape juice — urgently dangerous.
