Very friendly owners helped a first time dog owner - with a senior chiweenie rescue - learn about dry food options and gave us many samples to try. Went back to buy a winter coat and a harness and staff was helpful with harness selection. They were also very friendly to my dog when I brought him on our 3rd visit. He appreciated the treats too. I'll be back.
