A change in food aims to introduce your dog to a new diet – the approaches are as varied as the reasons for a change in food:

  • Different age cycles of the dog
  • allergies or food intolerances
  • switching to diet food
  • Previously fed variety is no longer produced
  • Desire to switch to a higher quality food
  • Picky animals and loss of appetite: changing food offers variety
  • No matter what reasons apply to your dog, you should think carefully about switching from wet to dry food or BARF beforehand

Switching from dry to wet food:

  • Conversion is usually problem-free
  • A high meat content is important

Switching from wet to dry food:

  • With wet food, the organism gets part of its water needs from the food. When switching, your dog should therefore get enough water
  • Our tip: For better acceptance, moisten the dry food with lukewarm water

Switching to BARF food or from BARF to wet or dry food:

  • Important: Nutrient and meat content should be similar
  • 0-diet for one day before the change: At least 8-12 hours break between meals

Changing from wet to other wet food/dry to other dry food:

  • Change is usually easier and faster

FEED CHANGE IN DETAIL

Age-related feed change

Over the course of a dog's life, it makes sense to switch from puppy to adult and later to senior food. Depending on the stage of life, your animal will require different rations of nutrients, as its needs and activity levels change.

BARF product tip:

Health-related feed change

Changing food in case of illness (diet food):

Dietary foods are not only intended for weight loss, but are also useful for special nutritional purposes: renal insufficiency, intestinal diseases, urinary stones or semolina, allergies and intolerances, obesity.

Changing food in case of intolerances or allergies (hypoallergenic food):

By elimination you can find out which feed ingredient
Your dog is allergic or intolerant to something.

HOW LONG DOES A FOOD CHANGE TAKE?

The duration of a successful feed change depends on the answers to the following questions:

  • How old is your dog?
  • How long did he eat the previous food?
  • Is the change in diet voluntary or for medical reasons?
  • How is your dog and his digestion constituted (robust or sensitive)?

Normally: 1 to 2 weeks – for very sensitive animals the transition may take longer.

Type and duration of feed change:

  • Changing the puppy's food – 7 to 10 days
  • Feed change for adult robust dogs – 7 to 10 days
  • Changing food for a sensitive dog – 1 to 2 months
  • Changing the food of a senior dog – 10 to 14 days
  • Switching from BARF to high-quality wet food – 7 to 10 days
  • Switching from BARF to dry food – about 7 days
  • Switching from dry to wet food – 7 to 10 days
  • Switching from wet to dry food – 14 days to 1 month

WHAT IS THE BEST WAY TO CHANGE FOOD?

For dogs, changing food is usually not a problem. Depending on the reason for the change, it can be done abruptly or gradually:

Always prefer a slow change to an abrupt one. It is gentler and gives the dog's body time to adjust to the new type of food. This allows the intestinal flora to slowly get used to the new food.

Health-related feed change

The quarter method has proven to be effective in the gradual transition:

  • Day 1 and 2: Replace a quarter of the familiar food with the new food
  • Day 3 and 4: Replace half
  • Day 5 and 6: Replace three quarters
  • From day 7: Your dog only gets the new food


If your dog is generally sensitive, extend the process to two weeks.

Changing the food for puppies

Changing food can be a challenge for a puppy. Therefore, you should feed the breeder's familiar puppy food for at least two weeks before adding a new one to the diet.


In order to irritate the gastrointestinal tract as little as possible, we recommend a gradual change over a period of one to two weeks: either in one-quarter steps or – for particularly sensitive stomachs – in smaller portions.

Switching between wet food, dry food or BARF

Gentle and gradual approach if there is no medical reason to rush. Long-term mixed feeding of wet and dry food is well tolerated by many dogs. Gradual transition to BARF to avoid digestive disorders in sensitive animals.
