Dofos announced that the new site will feature in-store recycling initiatives.
To mark its upcoming opening, the business said it was also offering the chance for customers to receive 40% off dog grooming and a £100 voucher.
The family-run business first opened in 1953. It previously operated from its flagship store at Blenheim Place, but relocated in 2015.
Dofos said that since the move, the “dynamic of the store has changed”.
It said: “We focused on pet foods with high meat and great nutrition and we dropped big brands made by big corps looking to make big profits in our industry with their food contradictory to our values as a business that cares for your pet
“Since then we have went from strength to strength as a company cementing in our mind we are doing the best for your pet. In keeping up with the times we have launched our online store and now deliver all over the UK.”
It added: “As our customer base has grown we have become more diverse as a company offering more services including our pet hotel l and a free in house delivery service for Edinburgh.
“We continue to strive for our values and beliefs as a company for the future and we have already set out a plan to use biodegradable packaging for all our in house packaged goods instead of plastic.”
