Can dogs eat fruit juice?
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.
If your dog ate more than a safe amount
Fruit juice concentrates are high in sugar. If your dog has drunk a small amount of plain fruit juice, watch for GI upset. Grape or raisin juice is toxic — call your vet immediately.
