I buy my collars on etsy - leather with the buckle engraved with his name and my phone number. I also have an apple airtag attached to it in case he gets loose, and he’s microchipped too. I don’t care for breakaway collars but I DO support quick release collars, and most dog daycare/boarding places will require you to have a quick release collar as well as relevant vaccines.

This is the last collar I got him, I like it a lot: https://www.etsy.com/listing/1108400795/leather-dog-collar-personalized-engraved?ref=share_v4_lx

This is the airtag holder I have, I flipped it so the rubber backing sticks outward preventing the airtag from getting dinged or taking damage or getting wet: https://www.amazon.com/dp/B09M6N6DJ9?ref=ppx_pop_mob_ap_share
