[QUOTE="claudine, post: 16956, member: 242"]The collar is grey and looks like plastic.\nUnfortunately, I don't know what brand is it. We bought it from the vet, I believe it's a Polish product.[/QUOTE]\n Okay. I want to find one that works. I read recently of making your own collar with a scarf and adding all these natural ingredients. When I find the exact remedy I will share it. It seems sensible enough but the problem for me is keeping the collar around the neck. With four dogs playing the collar needs to be glued on.
