Like any other supplement on the market, it is always best to speak to your local vet first. The Licks Skin & Allergy Dog Supplement has a good reputation on the market and it much like other supplements on the market moves in the direction of alternative health and welfare for your dog.
Note the directions on the supplement as it states that you should administer direct to mouth, in food, or in a separate bowl. Use consistently for 2-3 weeks to achieve desired results. The active ingredient in the supplement is 100mg of Curcumin. This has become very common in animal products which will also go under the name of Tumeric. Curcumin is the main active ingredient in turmeric. It has powerful anti-inflammatory effects and is a very strong antioxidant.
Oregon State University has a number of studies on the effects of Curcumin, however, these are human studies and not animal studies per se. Clinical trials in humans indicate that the systemic bioavailability of orally administered curcumin is relatively low and that mostly metabolites of curcumin, instead of curcumin itself, are detected in plasma or serum following oral consumption. The reason why it has become part of alternative treatments is that it does show that it inhibits mediators of the inflammatory response.
Licks Skin & Allergy Dog supplement also contains 700mg of Omega 3 fatty acids from Wild Caught Sardines and Anchovies. It also contains 100mg of Inositol which plays a role in helping the liver process fats as well as contributing to the function of muscles and nerves.
The products do not have many reviews however it is clearly aimed at the allergy market and its contents are well known to ease allergies in dogs. It is also used in multivitamins for older dogs for this reason. The price range is about $20 per box.
