PETA Takes Aim at Alessandra Ambrosio

Alessanda Ambrosio may be a gorgeous model ... but according to PETA, she's no role model.

The Victoria's Secret stunner was spotted this week walking her adorable puppy, but instead of the pooch's white fur, the animal was rocking a crazy pink and purple dye job!

While the puppy still looks happy, PETA isn't.

"What most people don't know is that dyeing a companion animal's fur can cause the animal stress and can lead to complications or allergic reactions that endanger the animal's health," the organization tells E!. "Our dogs and cats love us regardless of how we look; why not extend the same kindness to them?"

This isn't the first time the organization has blasted a celebrity for dyeing their dog.

Both Jwoww and Aubrey O'Day came under fire for the same thing earlier this year.
