HENDERSON (KSNV MyNews3) -- Today is a big day for a local dog named Onion as his fate will be decided.
An animal-rights group wants to take legal ownership of onion and take him to a dog sanctuary outside Denver.
The mastiff-Rhodesian mix killed Jeremiah Eskew-Shahan while his family celebrated the boy's first birthday on April 28.
Henderson officials say the activist group cannot claim rights because the owners released the dog to the city after the attack.
Henderson city attorneys also will argue that Onion has been acting aggressively while at the animal shelter and should be put down.
An attorney representing the dog says Onion could not be properly evaluated in a kennel because they believe he's scared and acting erratically.
