Is it safe to rotate my dog's food, or will it cause stomach upset?

It's actually not a bad idea to feed variety of food if she tolerates it well. The most important thing to do is transition the food slowly. This means that you add the new food into the old food slowly. You can do this over the course of a wee; where you increase the amount of new food until it is 100% by the end of the week. It may also be beneficial to add probiotics to the food while transitioning. This can be found at most pet stores. If you notice diarrhea and vomiting while transitioning food, then stop the new food and only feed the old one. You can attempt the transition again when the diarrhea stops. If she gets diarrhea or vomiting again, then it's best to avoid that particular food. It's up to you how often you want to do this (6wks vs every 3 months), because I don't know of any strong reason to do it more or less frequently. I've included a link below to a short article that may help you in selecting the best foods and gives good advice about feeding your dog. https://www.petcoach.co/article/what-to-look-for-when-choosing-your-pet-s-food/ I hope that helps.

That should be fine! As long as Chloe likes her food, has no GI issues like diarrhea, good skin and ears and is at a healthy weight there is no problem with variety. I recommend an AAFCO tested (vs formulated - should be written on the bag) food, I hope this helps!

It's best to stick to one protein source. That's because switching food too often can lead to GI upset in the form of vomiting and diarrhea. Dogs will get all the nutrients they need from a high quality dog food.

Yes that can work, but I would advise against rotating flavors and brands. That's because sudden changes in food can cause GI upset in the form of vomiting and diarrhea. It's best to stick with one brand and flavor. Dogs do not need their food changed :-)

Thanks for using Petco Pet Education Center, formerly Petcoach! This is actually not accurate. The reason is that most dogs are very sensitive to diet changes and it is best to stick with one good high quality balanced diet longterm instead of switching them frequently. Some examples of high quality balanced diets include Purina Pro Plan and Science Diet foods. Once you are feeding a balanced and complete diet, there is no need to add other ones or switching them. This will avoid the gastrointestinal issues that would come with changing diets on a regular basis. Good luck and have a great day!

No, it is not good to switch a dog's food every three months. Switching food can cause GI upset such as vomiting and diarrhea. It is better to stick with one type of food, and only switch it for a medical reason as recommended by your vet, such as with kidney disease. Royal Canin is an excellent food, I would keep feeing Simba that and not switch his food.

Rather than using a 50/50 mixture for a diet transition, I would instead ideally recommend starting 75/25 old/new food for 2 days, 50/50 for another 2-3 days, then 25/75 old/new food for another 2 days. Chloe is more likely to experience gastrointestinal upset without the more gradual transition. That said, it is possible that she could be perfectly fine with a more consistent 50/50 transition over 7 days. If she does not normally have a sensitive GI tract, you can try a 50/50 mix for 7 days, but if she does develop signs of a GI upset (vomiting, diarrhea, loss of appetite), a more gradual transition will be necessary. I hope this helps clear up any confusion!
