If you want to change your dog's feed, you should make the transition slowly. This can help the dog adapt to the new feed and reduce digestive tract problems. Specifically, you can do this: Gradually mix old and new feed: At the beginning, mix the new feed with the old feed, and then slowly increase the proportion of new feed. The mix should be changed daily, eventually transitioning the dog completely to the new feed. Change a little every day: You can also change the feed just a small amount every day until the dog is completely switched to the new feed. Use less new feed: If the dog is unwilling to eat the new feed, you can try replacing the old feed with a small amount of new feed, and then gradually increase the proportion of new feed.
No matter which method you use, the dog's transition process should last at least a week. This gives your dog's digestive system enough time to adjust to the new feed and reduces the risk of digestive tract problems. Finally, it should be noted that dog feed should be of high quality and appropriate for the dog's age, size, and activity level. If you're not sure what your dog's feed should be, it's recommended that you consult a veterinarian or professional pet nutritionist.
