How to transition your pet to a new food


It's important to slowly transition your pet to a new food so their system has a chance to adapt to the change. Some pets have no problem changing diet without transition, but others have more sensitive digestive systems. If you know that your pet has a sensitive tummy, then transition even more slowly than the recommendation below.

The transition period should be at minimum, ten days and could take upwards of two weeks, depending on your pet's sensitivity to change:

  • On day one, introduce 10% new food / 90% old food. Keep the food at this ratio for one or two or more days.
  • Next, increase the ratio to 20% new food / 80% old food for two or more days.
  • Repeat increasing by increments of 10% until you're feeding 100% of the new food.

If your pet experiences any kind of digestive upset during this time, try slowing down the process to let his/her digestive tract adjust to the new food. Some vomiting and/or diarrhea can be normal when introducing new foods as the digestive process and the naturally occurring bacteria your pet's body requires is a complex and delicate system. If your pet experiences any vomiting and/or diarrhea, be sure to reduce the amount of new food the next time you feed and overall, slow the whole transition period down even more.

If you are changing your dog from a raw food diet to a kibble diet you should not follow the above transition programme. The bacteria in the digestive system is different when your dog is on a raw diet to a cooked diet and so it is not recommended that you mix the two types of food.
