Abandoned by its owner due to its deformity of having only two legs, this dog is now teaching the world an important lesson.

Heroic two-legged dog who inspired injured troops to overcome disability dies peacefully

Faith never let her birth defect stop her and spent her life inspiring everyone she met: Helping injured troops deal with disabilities

A heroic dog who taught herself to walk upright on just two legs has passed away – after a lifetime of inspiring injured US troops.

Cute canine Faith gained a celebrity status as she often travelled to airports with her beloved owner Jude to welcome home returning soldiers.

Her incredibly positive attitude always cheered up the troops and even earned her an honorary title of E5 Sergeant for her work.

Before Faith was rescued by Jude and her family – the poor pup was born deformed at a flea market and the dog’s mum tried to smother her by lying on top of her – but Jude’s son Reuben grabbed the puppy and brought her home.

Despite vet’s advising the dog be put down due to her deformities, Jude and her family would not let that happen.

As Faith grew up, the family always kept an eye on her progress, making sure she would sit upright so she wouldn’t damage her neck and chest.

And it wasn’t long before Faith overcame the odds and was standing up straight and walking on two legs.

Her funny combination of a walk/hop/jog became a brave symbol across the globe for overcoming disabilities.

Faith was a busy dog – not alone did she provide support to recovering troops – she attended a kids’ reading programme and toured with the legendary Ozzie Osbourne.

Proud owner Jude said Faith took it easy in her later years but still popped to local airports when troops were coming home.

Her deformities did create more pain as she got older and her pain was increasing recently due to the discovery of cancerous tumours between her shoulder blades.

And the beloved dog’s pain was ended on Monday, when Jude believed the pain was getting too much for courageous Faith.

Jude revealed the sad news on her website: “It is with a very heavy soul and grieving heart that I must inform the world, and all of Faith the Dog’s friends, fans, family, and loved ones, that she has passed.

“When I have more time to give her a proper tribute I will do so. For now I ask that you continue to pray for us today. Thank you for your love and support.”

Faith was almost 12-years-old when she died, an unbelievable feat for a two legged dog who wasn’t supposed to make it past three weeks.
