Can dogs eat kale? Caution
Caution. A little kale is probably harmless for most dogs, but it can irritate the stomach and may contribute to bladder or kidney stones.
What to do now
- Watch for vomiting, diarrhea or changes in urination.
- Call your vet if these signs appear or your dog has a history of stones or thyroid disease.
Don't
- Don't make kale a regular treat.
- Don't feed it to dogs prone to kidney or bladder stones.
How to give it safely
Green beans or cucumber are better choices. If you share kale, give only a small amount, and not regularly.
Signs to watch for
- Vomiting
- Diarrhea
- Changes in urination
Why
Kale contains calcium oxalate, linked to kidney and bladder stones, and isothiocyanates that can irritate the stomach. Regular feeding may affect thyroid function.
