Yes dogs can eat bell peppers.
Bell peppers are healthy for dogs as well as humans.
My dog likes eating bell peppers and even my cat likes to eat bell peppers.
I feed my dogs vegetables and fruits once in awhile as a treat and the dog and cat gets health benefits when they are eating more than just cat or dog food.
Just about any human food that us humans eat the dogs can eat as well.
My dog and cat both also love Cantaloupe as well.
I slice up Cantaloupe and share with my dog and cat when we're eating cantaloupe.
I grow a lot of our vegetables and fruits so have plenty to share with them.
