Hi wtjham –
A healthy dog should be able to switch foods cold turkey with minimal digestive upset. All three of my dogs eat a homemade raw diet and get something different at each meal, none have any issues. When my oldest dog used to eat kibble I switched to a new brand at the end of each bag (about every 3 weeks) and rotated through different canned food toppers daily with no issues. My newest pup (just turned 7 months old) came to me at 8 weeks on Pro Plan – I switched her to raw cold turkey and she had no problems. To decrease the chances that your pups experience digestive upset you may want to mix in a spoonful of plain canned pumpkin and give a probiotic supplement during the first week or so of the switch. Good luck and congrats on the new pups!
