This list of ingredients and miscellaneous substances don't really belong to a specific category, but it's essential we don't overlook them. Some of them aren't well-known but can be extremely dangerous to dogs.

Xylitol, for example, is in most sugar-free sweets and chewing gum. Since it's so common, it's something you, as dog owners, need to know about so you can avoid it.

Like with the other seven categories, we have provided videos and explanations to help you understand why these foods are so harmful to dogs. If you'd like an overview, check out our free handout. We summarise the categories and the main problems dogs face with these foods.
