Dear readers,

A new year started off and we wish you happiness, joy and success. May the traditional wishes of “health” really come true.

This year again, we shall try to keep you informed about different and interesting subjects. As a federative organisation, it is essential that our members, the breeders, the judges, the exhibitors be kept updated with the activities organised by the national canine organisations, with the routine that makes their daily work or with the different working championships as we also want to focus on the work, the missions, the functions that our dogs are able to perform.

We shall keep taking time to make you a bit more familiar with our national canine organisations by allocating them a specific space. In the issue you are about to read, we have chosen to highlight our Ecuadorian member, AERCAN.

It is very important to know that some natural ingredients such as essential fatty acids, amino acids, vitamins, minerals and prebiotics can help to support problems such as allergy and pain. The advantage with those natural ingredients is the avoidance of side effects. Viyo Elite contains all those natural ingredients in a liquid and high palatable formulation to increase absorption and acceptance of those active nutrients.
