Should kohlrabi be raw or cooked for dogs?
Cooked. Cooking destroys the compounds that form from the glucosinolates in cabbage and can affect the thyroid in large amounts (Beasley, Veterinary Toxicology; Galanty et al. 2024). There are no studies on kohlrabi in dogs specifically.

Is kohlrabi bad for the thyroid?
In humans, it isn't expected to be a problem at normal amounts with enough iodine, according to a 2024 review. That review found only three studies on kohlrabi, none of them in dogs (Galanty et al. 2024).
