Listed as Non-Toxic to Dogs
ASPCA lists these common crops as non-toxic: basil, cilantro, dill, rosemary, thyme, sage, lemon balm, carrot, cucumber, zucchini, beets and Swiss chard, sweet potato, cantaloupe, strawberry, zinnia, snapdragon, nasturtium, and hollyhock.
Non-toxic does not mean a dog can eat as much as it likes. Any plant can cause vomiting if eaten in quantity.
Not on the List
Lettuce, spinach, peppers, eggplant, beans, peas, sweet corn, cabbage family crops, watermelon, pear, blueberry, raspberry, and blackberry have no ASPCA entry. Not listed is not the same as safe. It means ASPCA has not rated the plant.
Keep Dogs Out of Toxic Crops
- Grow onions, garlic, leeks, and chives in a fenced or raised bed.
- Pick up dropped apples, peaches, and grapes, and rake wilted leaves after pruning or storms.
- Plant a pet-safe herb bed where the dog spends time.
