Our team of jewelry professionals re-size each dog collar model by either adding or removing links to the chain. During this process our bench jewelers inspect the remaining links to ensure there are no issues or damage. After the collar passes our inspection requirements we complete the process by giving your collar a professional ultra sonic jewelry cleaning and polish if needed. Finally, we ship the designer dog collar back to you free of charge.
