This is Gluta. She's the happiest dog you will ever see in your life. Ever.
Gluta was rescued as a stray. Since then she's battled metritis - a condition that led to doctors having to remove her uterus - and cervical cancer.
But after receiving chemotherapy and having the tumor removed, she's back to being her happy, healthy self.
She's gained thousands of followers, and looking at the pictures of Gluta with her brother Gollum, we can totally understand why.
