I bought this necklace bearing in mind the rather positive reviews read here and elsewhere ... but we must be careful when its first use, it is not as harmless as he may appear so. My 9 month Labrador made the bitter experience. Just two days have put it, it was very itchy neck and had become apathetic. A visit to the vet, we found that it made a big allergy eczema necklace with a beautiful neck. Fortunately, he got over it! The collar may be good for a majority of dog, but not for all ... So to use with caution and do not hesitate to consult a veterinarian if you have any doubts, because the effects can be significant, s they are not treated quickly.
