Red dog collar with bone tag found in Dundee

Found this red nylon dog collar with a small silver bone-shaped tag on it this morning around 8:15am outside the V&A Dundee on Dock Street. It's a medium-sized collar, bright red with a black trim, a sturdy plastic buckle, and a well-used feel with a few scuffs along the edges. No brand logo visible on the outside. The bone tag is engraved with the name 'Rex' and a barely legible phone number on the back. The collar is clean but clearly worn from daily use. If this belongs to your dog, please get in touch; I’d love to help reunite you, especially since Rex might be anxious without his collar.
