Apple picking season is here and many families enjoy picking apples at the local orchards. But are apples safe for my dog? Yes, apples are a safe and nutritious treat for dogs. They are rich in vitamins A and C as well as being high in fiber. While the fruit is safe, you should avoid giving your dog the core with the seeds. The seeds contain cyanide, and while a few seeds are not likely to hurt your dog the long term effects of eating seeds can be dangerous. As with any fruit, be sure to give to your dog in moderation.
