Affordable dog food for sensitive skin: Iams, Purina One, or what?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Male | neutered | 1 year and 6 months old | 45 lbs

What dog food is better iams or purina one? I currently feed him purina one but it’s getting a little pricey and I’m thinking about switching to a new food. Also what other foods should I look into for him? He has sensitive skin issues.

Both are good foods. I personally feed my dogs Iams, so if you wanted to switch to that, it's fine to do. It's important to know when switching foods to do it slowly so that Scooby doesn't get any GI upset. Start by mixing 75% old food and 25% new food, and feeding that for a couple of days. Over the course of two weeks, gradually increase the amount of new food and decrease the amount of old food until he is eating the new food only. Other brands I recommend include Royal Canin and Hill's Science diet, but those would be pricier than the Purina One and Iams. I hope this helps!

    Thanks for using Petco Pet Education Center, formerly Petcoach! If he has sensitive skin issues, you could consider something like Science Diet z/d. However, this diet while good, it can be pricey. You could consider instead the Purina Pro Plan focus sensitive skin diet which is less expensive and still of very high quality. Good luck and have a blessed day!

I like Purina ProPlan Sensitive Skin & Stomach. I have had many clients rave at how good it is for dogs with sensitive skin. You could also try Purina One SmartBlend Sensitive Systems but I don't as much experience with clients using it. It is much less expensive that the ProPlan.

Congratulations on your new puppy! Pepe Le Pew is absolutely adorable!! Iams puppy food is a perfectly fine food to feed him. I would recommend if you wanted to switch foods to wait two weeks before you do that. This was he gets comfortable in his environment before switching anything. You can do Iams, Science Diet, Nutro, Eukanuba and even Royal Canin. These companies do a lot of research on foods and are well balanced. Congratulations again and thank you for using Boop by Petco!

Thanks for using Boop by Petco! The diet I prefer for this is the one made by Science Diet called sensitive skin and stomach diet. However, what I have found the most helpful in reestablishing a nice shiny coat is using fish oil daily. You can get the commercial ones sold online or at your local pet store. This works great. Good luck and have a great day!

Hello. My dog Winston has a sensitive stomach and sensitive skin. I am currently feeding him the dog food brand Wholehearted. I believe that the food making him sick. What is a good dog food brand for sensitive stomachs and skin.
I'm sorry to hear Winston is having these issues! A good first step is to schedule a vet visit for him to rule out any underlying conditions that could be causing his symptoms in addition to food. Your vet can also work with you on a food trial if it is suspected that a certain ingredient is the cause for the problem. For general sensitive stomach/skin, Science Diet has a formulation that addresses both. You want to make sure to gradually change the diet over a period of 7-9 days to avoid additional stomach upset, gradually adding in more of the new food. It can also take up to two months for a food trial to see results.

As long as it is a name brand food with an AAFCO label on it. This means it has been tested and meets specific standards. Typically royal canin, Purina, science diet, and Iams qualify for this. Be careful switching foods without suddenly as this can cause diarrhea. It is best to mix them and gradually switch it over a week

As you've experienced, diet changes can certainly cause some changes in stool volume, and for some dogs, can cause a bit of vomiting and diarrhea. When it comes to the countless brands of dog food on the market today, it's overwhelming to pick one for your pup. I recommend brands that have been formulated by a board-certified veterinary nutritionist, are manufactured in their own facility (less cross-contamination that facilities that manufacture numerous formulations), conduct AAFCO feeding trials, and meet WSAVA guidelines. When it comes down to it, the brands that meet those criteria include Hill's Science Diet, Purina, Royal Canin, Eukanuba, and Iams. As a result, I would recommend switching Lilly over to the Science Diet puppy food. Just remember that anytime you switch foods, be sure to do so by gradually mixing the old and new foods together over a 5-7 day period. I hope that everything goes well!

My dog has been diagnosed with food allergies since he was a puppy. The vet told me which foods it probably would be and had me put him on Purina pro plan sensitive skin. It worked and he stopped itching, but a couple weeks ago he refused to eat his
Hi, I would either try to reintroduce Purina food gradually and if not tolerating it, source another hypoallergenic diet such as Hill’s Z/D for example. Have a look to see if wet food is available in the Purina range, there definitely is in the Hill’s one. If itchiness is severe and distressing, I would recommend to see your vet so he can dispense some medications to help promptly. Hope this helps and that things settle again soon.

my dog as been having dry skin and i was told he should have fish in his food for the oils. i do feed him science diet but the do not have fish. what is a better alternative to change his food to that comes in fish?
Science Diet is an excellent food but as you have noticed their over the counter foods typically don't have fish. They do have a prescription diet with fish but it can be expensive. I included a couple links to a couple different types of food that contain Salmon. https://www.chewy.com/purina-pro-plan-focus-adult-sensitive/dp/128666 https://www.chewy.com/purina-one-smartblend-sensitive/dp/37688 Thank you for using Boop by Petco.

HI there. I would recommend using a true weight loss diet and not a "weight management" or "healthy weight". You should use the weight loss diet until he is his ideal weight then you can transition to a management diet. These diets are expensive but they are not meant to be a long term solution so keep that in mind. If you feed the correct amount it shouldn't be too horribly expensive. You must feed him to his "ideal weight" and not the weight he is currently. So read the instructions on the bag of food carefully. Feed him this diet only - no treats or bones or people food. I would suggest Puirna OM or Hill's w/d. These are prescription diets and should be prescribed by your vet but I have recently come to find out you can buy them on Amazon without an Rx. They should not make his coat or skin poor. If that is a recurring theme then he may have an underlying condition like hypothyroidism causing that (could also be why he is heavy) so you may want to consider having his thyr

As far as commercial breeds that come to mind, Wellness would be a good choice to meet your requirements. It is a little pricey, but I feel that it is a very high quality diet. A raw diet would also be an option, but would definitely require a significant amount of financial and time investment (though there are commercially available raw diets as well now). Hope this helps.
