Shop/store owners - what moves the needle for your when selecting new products for your stores?

I’m starting a gourmet dog treat brand with beautif dog treats filled with meat - the good stuff dogs actually want - they’re shelf stable up to 2 - 3 months too. I’ve emailed about 20 stores in my area I think would be a perfect fit - no response.

I’ve a full time job so I cannot drive around going to all these stores - I’ve to make the treats.

Would calling help? Would sending out samples with a kit to the stores work?

Targeted stores are

• specialty stores
• gift shops
• pet stores
