Back in 1960 a dog fancier visited Grannick's Pharmacy and explained that her dog would become nervous before every show and start chewing and licking his coat. She asked if there was anything available to help stop him. No such product existed, but in the days when Irv Grannick learned his profession, pharmacists regularly prepared their own compounds and ointments. He tried different bitter flavorings until he came up with a formula that worked. Word spread among dog fanciers and breeders and before long friends were encouraging Irv to market "Grannick's Bitter Apple". His original "manufacturing plant" was in the kitchen of his home and his wife, Mary, wasn't thrilled. Over the years Grannick's Bitter Apple has grown into a full line of taste-deterrent grooming cosmetics for pets. Many copycat products have come and gone because pets soon acquired a taste for them. Only Grannick's Bitter Apple works and keeps working.
