A study conducted by Invetus on allergic dogs in Australia

Pets are a source of love and joy. Unfortunately, those loved creatures may cause bad odor and allergies. betterair comes to the rescue of pets and their owners. Field household study - evaluation of Enviro-Biotics™ efficacy on atopic dogs 

The objective of this Enviro-Biotics™ study was to evaluate the owner’s perception of their allergic dog’s pruritus (atopic skin condition) and malodour following regular use of Enviro- Biotics™ over a 21-day period. This study has also evaluated the population pattern of Staphylococcus pseudintermedius and Enviro-Biotics™ in a subgroup of the study animals.

Dogs with atopic dermatitis have been shown to have less species of bacteria on their skin compared to healthy dogs, therefore contributing to a compromised skin barrier leading to increased itch and skin odour. Atopic dogs are also at a significantly increased risk of developing skin infections (pyoderma).

This pilot study was aimed to evaluate the effects of regular topical application of Enviro-

Biotics™, on dogs with atopic dermatitis and their sleeping area.

Furthermore, the assessment of specific bacteriological cultures, pruritus (itch) scores and owner’s perception of odour on skin and bedding before and during the use of the product over a 21 day period, were evaluated.

Pruritis assessment:

The Enviro-Biotics™ treatment reduced the pruritis incidence by 0.6% per day. The reduction was found to be statistically significant (F1,11.01=7.05, p=0.022, Figure 1a).

Odour assessment:

Odor assessment has exhibited a decrease of 0.57% per day ( Figure 1b)

Bacterial culture assessment:

The concentration of Spseudintermedius of skin samples taken from the dogs declined over Day 7-21, while the concentration of Enviro-Biotics™ remained constant over this period.


The results are very encouraging considering the relatively short assessment time frame for a chronic condition.

A statistically significant decrease in Pruritis scoring is exhibited together with a clear decrease in odour and in S. pseudintermedius (primarily a pathogen for domestic animals, but has been known to affect humans as well) while Enviro-Biotics™ remained constant.

This study was conducted by Invetus, the largest Australasian veterinary contract research organisation (CRO) with sites throughout Australia and New Zealand and managed by Orivet genetic pet care, Australia.
