It was a Christmas to remember for Caroline Manzo, but for one very sad reason.
The former Real Housewives of New Jersey
star and her family said goodbye to their beloved dog, Austin, who fell ill over the holidays.
"My little man, feel better baby," reads the caption of an Instagram photo
posted by Manzo's 25-year-old daughter
, Lauren, on Christmas Eve.
Later, on Christmas day, Manzo, 52, Tweeted a sweet shot
of the pup sitting on Santa's lap and wrote: "RIP my beautiful little puppy, you were so loved. Santa has a new sidekick."
The dog's passing appears to have affected the entire family, who are set to star in their own Bravo spin-off, Manzo'd With Children
. Manzo's son Albie, 27, posted a shot of the dog's very own Christmas ornament on Instagram
, writing, "Lost our little guy today, been with us every step of the way for the last 17+ years. Gonna miss you buddy."
