Most of my dogs wear Lupine collars and we've actually put the warranty to the test. Sky broke the clasp on his and we sent it back to the company. In about a week we received a brand new collar, no questions asked.
Samba wears a super soft Planet Dog collar to safeguard her sensitive skin.
Don't think our new boy Sebastian is being left out. When we found him he was wearing an old faded collar. The print was worn off on most of it, so he's also getting a new collar. When I bought Tsar's collar several years ago, I liked it so much that I bought two. One has never been worn and it will now be Sebastian's.
