Dog Week: Sci-Fi Saturday: Discontinued Models

Suzanne and Rick had full lives, but as age
Crept up on them, they did admit some need.
Rick hated carebots, though. Then, on a page
In Cyber Fancy, their son chanced to read
An ad for a new breed of home-care tech:
NurseDogz! Thus came to their old house a pair
Of fuzzy poodles, programmed well to check
Blood pressure and such other stats as their
Physicians liked to know. And they were cute!
But soon Rick had subverted Willow, who
Reverted to her yappy, happy roots
And lied on her reports. Then Gracie, too
Developed glitches. Suzanne's crafty hack
Let her shop Amazon behind Rick's back!
