Yes white rice is good for dogs.
You can feed your dog some white rice and even some chicken.
Some dogs go on a white rice and chicken diet which is healthy for them as well.
You can just dip the chicken into some boiling water to kill off bacteria and then feed the dog the basically raw chicken and white rice.
Or just feed them the white rice.
Just make sure the white rice you feed to your dog is fully cooked so it's easier for the dog to chew and digest.
