The full picture
Watermelon is 92% water and makes a brilliant summer hydration treat, especially frozen. It's low in calories and rich in vitamins A, B6, and C. The rules are simple: remove all seeds (they can cause intestinal blockage if enough are eaten) and don't let the dog eat the rind (tough on the digestive system, can cause blockage). Seedless watermelon is easiest. Chop into appropriate-sized cubes and consider freezing for a hot day.

Why the seeds and rind matter
Watermelon seeds can cause an intestinal blockage in sufficient quantity, particularly in small dogs, and the tough green rind is difficult to digest and a choking/obstruction risk of its own — seedless watermelon flesh, cut into manageable pieces, is the safest way to serve it. Frozen watermelon cubes make a good hot-weather treat.
Does size or breed matter?
Obstruction risk from seeds or rind is proportionally higher for small and toy breeds given the same amount swallowed. No toxicity concern from the flesh itself at any size.
