If your dog has eaten any of these foods, go to your vet. Also, it would be advisable to make her vomit. This way she wouldn't digest the toxic food and won't damage her body.

Although most people believe dogs shouldn't get any food from the table, it's not entirely true. Some human foods do not harm our dogs.

Meat and fish if it doesn't contain any salt or other spices. Vegetables, such as cucumbers or potatoes, fruit, such as apples and watermelon are also good for dogs. Be sure not to give your pup any seasoned food, also avoid food with seeds or other not safe to eat vegetable and fruit parts, such as an apple stalk.

In general, food from the table itself is not doing too much harm. The problem is that people tend to give food directly from the table. This way the dog learns to stay next to a table and patiently wait for some tasty bits. If you want to give some food to your pup, it's better to use it during training sessions or place it into her bowl or crate. We advise against giving any food while you eat, as most dogs quickly understand that following your every movement while you eat is beneficial. Most owners don't want their dogs to be hanging around while eating.
