My dog finished Hills RX. Can I switch to regular Science Diet?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Male | neutered | 20 lbs

I have a prescription for my dog for Hills Science Diet RX food. He had an intestinal virus. It is for 12 weeks. He likes it but I am wondering if i feed him the regular Hills food afterwards if it will still help. is there a large difference between the two foods?

If you have been feeding the Hills prescription food, you can always talk to your doctor about continuing this food. Yes, there is a difference between the prescription diets and regular food, but the regular Science Diet food is high quality. It will be less expensive to feed Science Diet sensitive stomach formula than to continue on the prescription food. You could always try a small bag of the regular food, and if Spartacus does not do as well, you could switch back to the prescription diet.
