Many years ago we purchased some Lupine collars and leads for the doglets. Fairly expensive but very pretty, though not indestructible were advertised as being pretty un-chewable. We’ve been impressed with how long they have lasted and even Kato only needed new ones because
she’s spoilt had grown. Apparently they are made from the same stuff they make rock climbing gear out of.
All we will say is - don’t ever go rock climbing with Frodi.
