My puppy is becoming aggressive when guarding their food
Dr. Lauren Bleaken a answers questions on an older puppy guarding their food.
If your dog or puppy does show some aggressive behaviour around food, the good news is that you can train out this behaviour
Start with giving them a dog toy and reward them with a treat for giving it back to you and allowing them to be touched when they have the toy. Then build this up to treats, then food.
