What You Need to Know
Tofu is made from soy and contains isoflavones — plant compounds with mild estrogen-like activity. Occasional small amounts are unlikely to cause harm. Regular large consumption may affect thyroid function and hormonal balance especially in intact female dogs. Always use plain unflavored tofu. Silken tofu is higher in water content and lower in protein than firm tofu.
Breed-Specific Notes
Avoid in dogs with thyroid conditions or hormonal sensitivities.
