All our products are specially formulated in two sizes: Small/Medium breed for dogs weighing less that 50 lbs/22.5 kg and Large breed for dogs over 50 lbs/22.5 kg

We use your dog’s weight to make sure it receives the correct dosage, so that our patented BIO-tract® technology can optimize the effects of the probiotics.

So if your dog’s weight is greater than 50 lbs/22.5 kg, you need OZLOO for large breeds, delivering two billion CFUs; but if your dog’s weight is less than 50 lbs/22.5 kg, OZLOO for Small/Medium breeds is required, delivering 1 billion CFUs of probiotics
