Remember, you not only have to remove the popcorn texture, but also redo the ceiling in some other texture. 1) how much the contractor you choose hates removing popcorn or textured ceilings - some charge $1 or so/SF extra just because they hate it.
Bananas are fine for dogs to eat. Dogs are omnivores, and most fruits are safe for dogs to eat (except grapes). Bananas are a good source for vitamin K, potassium, and other vitamins and minerals. Large quantities may cause stool problems however and is not recommended.
Dogs can eat even banana peels, especially if they find it in the trash - one more reason for a dog to learn what can and what shouldn't be done. Banana peels are not toxic for the dogs, but they should be avoided - banana peels are not digestible by the dogs and can cause intestinal obstructions and other health problems.
