Aspen Pet ヘビーデューティープロングカラー交換用リンク 3個入り

These links fit perfectly and made the collar much easier to adjust, so the prongs sit flat instead of digging in. The extra three links were enough to give my dog a comfortable fit without any pinching.

My boy’s collar was pinching after he put on a few pounds, and these links gave the extra room we needed. They clicked in easily and feel just as sturdy as the originals, though I wish the pack came with a fourth link for bigger dogs.

Was hoping these would give a bit more flexibility, but the heavy-duty plastic feels sturdy enough for daily walks. My dog's collar is definitely more comfortable now with the extra length, though I wish the links clicked together a little more securely.
