What makes OZLOO the right choice for your dog?


No one-size-fits-all

As a team of passionate pet lovers, we‘ve taken a more personalised approach towards your dog’s health, because a more individualised formula based on breed size is very important for their overall wellbeing. Using decades of pet nutrition research (and a little common sense), our founder worked with top veternarians to create the range of OZLOO dog supplements .

Correct dosage

  • We use your dog’s weight to make sure it receives the correct dosage.
  • If you dog’s weight is greater than 50 lbs/22.5 kg you need OZLOO for Large breeds and if your dog’s weight is less than 50 lbs/22.5 kg you need OZLOO for Small/Medium Breeds.

Veterinary formulated

  • Exact formulation of supplements was designed by veterinary doctors

  • Patented Bio-tract® protection and time-release technology ensures that the active ingredients are able to pass through the harsh stomach environment and can colonize in a dog’s small and large intestine, where they’re needed most, and are released slowly over an 8-10 hour period. The Patented BIO-tract® delivery technology consistently delivers as many as 15 times, or more, the number of live, viable probiotic organisms compared to plain/standard capsules. (as repeatedly demonstrated through in vitro lab testing)

The Science Behind OZLOO

All our supplements are vet formulated using BIO-tract® patented technology.

From taste, to efficacy and absorption, we’ve used science and technology to ensure the best possible outcome for your dog’s health.

First time owning a puppy?

The first four months of a puppy’s life are critical, as this is when the main growth and development happens.

Your puppy will go through many stages on their road to adulthood – just like a human baby does, and from eight to nine months, the main growth for larger breeds occurs in the skeleton and organs. Giving your puppy the best during this first 600 days (or approx. 60 days gestation + 18 months puppyhood) is essential, so set them up to have a healthy immune and digestive system from the word go.
