Food safety
Can dogs eat coconut?
Yes, but be careful
Small amounts of flesh or oil aren't harmful, but it's fatty and can loosen stools.
Being honest about this
Dogs differ, and amount matters — a crumb of something rich is not the same as half a packet. Treats of any kind should stay under a tenth of what your dog eats in a day. If you're unsure, your vet would far rather take the call.
