For some time after the medical treatment, Eva felt better. She came home and started performing her normal activities. She even went for regular walks with Erin, not displaying any sign of weakness.

But then, the one thing that Erin was afraid of happened! Overnight, Eva had sudden seizures and her condition deteriorated. 

She fell into a deep coma and had no response to any stimuli. Sadly, her body was too weak to fight this battle, and just a couple of hours later, Eva passed away.

Erin was devastated when she realized that her brave girl was gone. 

"This world is not fair. It is cruel. This wasn't supposed to happen. Our baby is gone and now we have no one come and be held with us. We don't have our kisses. I don't have my girls incredibly soft fur. She was so delicate. So dainty," she wrote on her Instagram.

Despite her sudden death, Eva will be remembered for her bravery forever. She was Erin's angel guardian who saved her life in every way possible. You will be remembered, good girl!
