The dog microbiome, i.e., the balance of microorganisms in the gut, is an essential factor influencing how long it will take for your dog to adjust to new food. A sudden transition of food can cause a change in the dog’s microbiome, temporarily leading to health problems like stomach upset- diarrhea or constipation, vomiting and regurgitating, and even decreased appetite.

Here’s a pro tip to avoid this kind of situation: ‘Gradually’ switch to the new diet to give the dog’s system some time to adjust to the change. How gradually should you switch? Don’t worry; we have got you covered! The trick is to simply mix old food with new ones. Follow the 7-Day Transition Schedule for dogs and keep your dog happy and healthy.

  • Day 1 – Day 2: 25% new diet and 75% old diet
  • Day 3 – Day 4: 50% new diet and 50% old diet
  • Day 5 – Day 6: 75% new diet and 25% old diet
  • Day 7: 100% new diet

It is usual for a dog to take more than a week to recover from the transition phase. While some dogs do not have any issue switching meals, others with sensitive tummy or food allergies may not be so fortunate. Depending on your dog’s health, it may take only a week to even six weeks to fully adjust to a new meal.

However, if you notice your dog exhibits any sign of discomfort during this transition period, you should allow more time for your dog. Monitor your dog’s activity from time to time. In case of extreme health issues, better make an appointment with your vet if your gut instincts tell you something is off. Trust your instincts!

As dogs continue to grow, their nutrient requirement levels change, so it is essential to switch to a different diet accordingly. Puppies entail a higher amount of food to keep up with their developing stage.

Unlike adult dogs, that is quiet, requiring just the amount to carry on with their health and weight. Pregnant or lactating dogs would have diverse food necessities. Sometimes dog owners want to improve the quality of the food to avoid nutrition deficiency or toxicity. Again, dog owners might switch to a new food as dogs might develop certain allergies to some products, though it is not frequently observed in dogs.

Stool Color

A change in diet may change the poop color. If you notice a dark or bloody stool for more than three days, you should consult with your vet.

Vomiting Or Regurgitation

Dogs might throw up food because the new food isn’t adjusting to their body system. That being said, consult a vet if this reaches an extreme level just to be on the safe side.

Decrease In Appetite

It is common for everyone to have a loss of appetite when sick. Similarly, for dogs, a transition to different food causes stomach upset in the first place, and they become sick, so their urge to eat decreases as well.

Pick The Right Commercial Food Brand

Picking the right food brand is a factor that will help the dog adjust to new food. A low-quality food comprises artificial ingredients that might irritate the dog’s stomach. This will make it hard for the dog to adjust to the food, no matter how gradually you introduce it or how much mixing is done.

As a general rule, if appropriate nutrition is provided, the body automatically adjusts to the meal more smoothly. So, a high-quality food brand is very much important.
