How to Switch From Purina Strategy to Nutrena

Occasionally, a dog owner may decide to switch a pet from one type of food to another. For dogs with sensitive stomachs, simply replacing a bowl of Purina with one of Nutrena may cause the dog to experience digestive upset. For the best health of the dogs, he or she must be switched over gradually from their current food to a replacement food in order to avoid problems like stomach upset and incontinence. This process can take up to ten days but is well worth the time.

  On the first day of the food switch, give your dog three parts Purina and one part Nutrena. Allow the dog frequent access to the outdoors, and observe him for any signs of cramping. Repeat this process for a total of three days.

  On day 4, feed the dog two parts Purina and two parts Nutrena. Monitor him for any signs of cramping or discomfort. If signs of gastric upset are present, move back to step one for a few more days. If all is well, continue with a 2/2 ratio until day 6.

  On day 7, give 1 part Purina and 3 parts Nutrena. Continue with this ratio until day 9 if the dog appears to tolerate the formula well. If stomach upset occurs, revert to step 2 for another few days.

  On day 10, give 4 parts Nutrena. Monitor the dog's stools and allow him frequent visits outdoors. If stools remain firm and no stomach upset occurs, continue to feed the dog only Nutrena.
