Yes, The Flinstone’s dog was Dino.  In this case that is not what we are referring to.  We are referring to the acronym DINOS
D– dogs
I-in
N-need
O-of
S-space
From the Dogs in Need of Space website,
“Dogs might be DINOS for a variety of reasons, such as:
Medical: illness, injury, surgery, or rehab
Occupation: Service and Working Dogs
Training: learning polite leash manners
Age: issues such as arthritis, vestibular disease, or blindness
Behavioral: fear, anxiety, re activity, intolerance of other animals
DINOS are GOOD dogs, they just need space!”
