IG Model Liziane Gutierrez’s Tiny Dog Maced by Home Intruders During Burglary

Instagram model Liziane Gutierrez and her 10-lb pooch fell victim to some nasty crooks who not only broke into her home but decided they also needed to mace the pup in the process.

Check out the video, obtained by TMZ, showing 3 men break into Liziane’s Vegas home Thursday night through a back door. You see her maltese, Duchess, approach the intruders in a friendly manner only to be blasted with pepper spray.

From there, the men rush upstairs and into Liziane’s bedroom, ransacking her closet and making away with Gucci bags, a Rolex, a gold chain and designer sneakers.

Thankfully, Liziane was at the gym at the time of the incident … but she tells us the men made away with over $50K in luxury goods. She called the cops as soon as she got home.

As for Duchess, she was taken to the vet — given a bunch of baths and some medication for her lungs and eyes — we’re told she’s still having a tough time recovering and isn’t yet back to 100% … though things are looking good.
