-Sherry and the Gemini Family
OUR FUR TEAM
Four legged work friends had the tough job of keeping us tension free and on our toes. They fulfilled their job admirably as the Gemini mascots.
Jake
Jake is the newest 4 legged member of our Gemini family. December 24th, 2018, Jake, his mom and four siblings were fostered when they were 4 weeks old by Sherry for 5 weeks. Jake the vocal one became a permanent family member. He goes to work with sisters Sadie and Bow. Loves to play ball and ruff house with the others. Really loves Scott the UPS man…waiting for the truck to drive up and rushing to the back door to greet him!!! No treats just ruffles!!!
Sadie & Bow
Sadie (Tan) and Bow (brindle) were being fostered by Sherry and the gang at Gemini. They were being treated for heartworm and needed to complete the treatment before being set up for adoption. Needless to say they became permanent residence of our Gemini family in the Spring of 2016.
Willy†
Willy was a Shiatsu / Poodle mix, He was a the dog with the great responsibilities, visiting each of us every morning for a little pack bonding, watching out for us with one eye open whenever possible, and greeting visitors with a wagging tail. Life was tough being THE Gemini mascot! We miss him dearly. Aug. 9th 2002, Aug. 10, 2018.
Casey†
Casey was the original Gemini dog, a multi-heritage combination of intelligence and friendliness with a weakness for snowballs. He could sing with the best of them when the Beach Boys’ Good Vibrations was playing on the radio.
Cheddar†
Cheddar was the next in the series, a personable Australian Shepherd with an uncontrollable weakness for doughnuts mixed with an endless supply of white fur. A trip to the stockroom building without Cheddar to escort you just wasn’t worth making. She accompanied Casey on duets but may have been slightly off key.
Kes†
Kes was next in succession, a used an abused Bluetick coon hound that went from scared and lost to all time champion couch potato and elbow nuzzler. She was always around to help get rid of those tasty bones and leftover lunch tidbits. Her distinctive vocalizations were unmistakable.
