Items you will need

  • Old dog food

  • New dog food

Feed your dog the same kind of food every day. Unlike humans, a dog's digestive system cannot handle changes in food. It can cause upset stomach, vomiting and diarrhea. When switching to a new food, gradually transition him to the new food by mixing portions of both foods until you slowly phase the old food out. Protect your dog from getting sick while changing dog food brands. Most dog food changes will occur from life changes. Such as: When your puppy grows up and is ready for adult dog food, or when your dog ages and is ready for senior dog food, or a dietary change recommended by your veterinarian due to allergies or obesity. Here are the simple steps that will make this an easy transition for your dog.

Day 1 - 3: Mix 75% old dog food with 25% new dog food.

Day 4 - 6: Mix 50% old dog food with 50% new dog food.

Day 7 - 9: Mix 75% new dog food with 25% old dog food.

Day 10: Feed 100% of the new dog food brand.

This slow schedule will allow your dog to adjust to the new food without indigestion, diarrhea, or constipation.

Consult with your veterinarian if there are any problems during this transition period and follow his advice. If you have any leftover old dog food, you can throw it into your yard for the birds!
