Kale
CautionVerdict
Very small amounts only — isothiocyanates and oxalates are concerning.
Toxic principle: isothiocyanates, oxalates
Source: ASPCA
Verdict
Kale contains isothiocyanates (GI irritants), oxalates (kidney stone risk), and calcium oxalate crystals. It is also a goitrogen, potentially affecting thyroid function with regular feeding. While a small piece of kale is unlikely to harm a healthy dog, it is not an ideal food and should not be fed regularly or in large amounts.
Symptoms to watch for
- • gas and GI discomfort
- • vomiting (larger amounts)
- • urinary crystals (chronic)
What to do
Occasional small amounts are not an emergency. Do not include kale as a regular part of a dog's diet. Dogs with kidney disease or thyroid conditions should avoid kale.
