That depends, There are many factors that influence how quickly you will see results. Such as severity of condition, immune status, diet, stress levels, age, breed etc.
The Skin Support is a pungent formula and sometimes you need to use for a few months to see systemic results. Healing from Allergies/Food intolerances is an immune issue, not a skin issue (the skin rashes are a result of an immune reaction). So I always recommend food allergy tests as 98% of dogs with skin allergies have them. Continuing to feed food that trigger a negative immune response will only further the intolerance and exacerbate skin symptoms. I recommend Easy DNA labs (Australian Based) Their food Allergy/Intolerance tests are very affordable and comprehensive (around $150).
With conditions affecting the skin it could take up to 3 months to see visible results (at the most) as the skin is the slowest healing organ in the body. It is very common especially with infections involving the ears and skin, for it to take a couple of months to fully heal.
As herbal medicine is aimed at fixing the root cause of the illness instead of just negating symptoms, it is not instant. Patience is key, but if you aren't seeing results after 12 weeks, please contact us and we can reformulate the medicine to suit your pets individual needs, or you may have to increase the dosage. INDIVIDUAL RESULTS MAY VARY.
