What is the microbiome?
The microbiome is an ecosystem, located in the pet’s digestive tract, containing billions of microbes and other microorganisms — including both desirable and undesirable bacteria unique to each pet.
Each pet has their own unique gut microbiome!


Science-backed nutrition
Hill's is committed to nutritional excellence, and upgraded Science Diet foods with ActivBiome+ Multi-Benefit includes an AAFCO feeding trail nutritional adequacy statement.
Now every bag of our Science Diet dry food will carry an AAFCO feeding studies claim. This is the ‘gold standard’ for determining nutritional adequacy.
Transitioning your pet to a new food
There will likely be a time when your pet will need to switch to a new food, whether it’s to a therapeutic nutrition, a new formula or they just need a food that better suits their life stage. Pets should gradually transition to new food to avoid stomach upset. Here are some tips for transitioning your pet to a new food.

Determine the right amount per serving
Make sure that you’re not overfeeding your pet, and the portions they get are appropriate for their weight and health needs. Your veterinarian will have the best recommendation on serving size, but you can also check the feeding guide on your pet’s food packaging.
Follow this 7-day transition schedule
Once your portions are correct, gradually decrease the amount of current (old) food while increasing the amount of new food. Be patient — if it seems like your pet needs a little more time, add an extra day or two to the schedule.

DAYS 1-2

DAYS 3-4

DAYS 5-6

DAY 7

Consider making your pet’s dry food more like wet food
While it’s not a necessity, some pets are a little more stubborn than others, and a little wet food can make all the difference. To avoid going over their daily caloric intake requirements, be sure to check with your vet on the proper serving sizes.
Combine wet & dry food
Try feeding your pet the dry kibble version of the same diet and softening it with the following ratios:
Mix Option | Dry Food | Wet Food |
---|---|---|
Crunchtime | 95% | 5% |
A Bit of Bite | 90% | 10% |
Soft ’n Chewy | 80% | 20% |
Add the following “enhancers” to make your pet’s dry food more appealing
Before adding any of these to your pet’s meal plan, check with your veterinarian to make sure it is appropriate for your pet’s diet. Added properly, it should make up 10% or less of your pet’s daily calories (kcal).
