As dog owners, we must understand that we frequently share our lives with dogs by owning a dog companion. Moreover, we even eat food in front of them! Eating food in front of your dog doesn’t mean that everything in your plate will be safe for your dog. There are plenty of human food that can pose a life-threatening risk if consumed by dogs.
In this Lulu Spot guide, the dangers associated with the worst human foods for your dog will be analysed so that better decisions can be reached based on veterinary knowledge.
