My shed door looks like a SS shop display. I've had 26" Mastiff collars down to 12" whippet collars and all the sizes in between.
I've had training leads, tracking leads, agitation harnesses, slip leads, custom couplings and a whole range of made to measure collars.
The only thing to ruin SS stuff is dogs teeth! This I've learnt the hard way, numerous times.
With regard to the collars being to big and heavy, you just get them made in lesser thickness say just 3 ply.
The fittings come on brass or steel depending on you preference.
You can have what you want, you ask and pay for it, Stron
