The store is the fifth outlet to date for the pet food brand, and sells a variety of pet goods such as food, toys, and accessories.
The new site also features a bespoke health and wellness service offering “advice, guidance and microchipping” to local pet owners in Llandeilo and the surrounding area.
The newest Burns shop has opened on Crescent Road in Llandeilo, and is said to be a “short walk away” from the main high street.
John Burns, founder of the brand, said: “Launching a fifth pet store in the stunning location of Llandeilo is exciting for us, especially after such a strange and tumultuous year for the area and the country itself.
“We’re hoping that the new Burns Llandeilo Pet Store will become a favourite in the community and provide pet owners with everything they need to support their healthy, happy pets.”
