"There was an accident with him this morning and it's nothing that anybody could have done anything to prevent, so it's no one's fault," she continued, adding, "He hopefully didn't suffer -- I feel like it was pretty quick."
The internet personality went on to call Tooie "the best puppy," who was "so funny" and had "such a personality."
JoJo also recalled some sweet memories of her puppy, sharing what was Tooie's "new favorite thing to do."
"Anytime I would go get ice in my freezer like for a coffee or for a water, he would run over, and he would hear the door open, and he would sit there and if I closed the door, he'd get really sad," she said. "He would want an ice cube, every time!"
"He would make breakfast with me in the morning," she continued. "He was so funny. He would just, like, fall down the stairs all the time. He really did have such a personality."
As she mourns Tooie's passing, the "Dance Moms" alum noted that she's "going to try to put a strong, brave face on."
"It's not going to be easy because he's the first puppy that I've ever lost that I've been really devastated 'cause I've been close to him," JoJo explained. "Our other dogs that have passed away, I wasn't really close to."
"My vibe's going to be off today -- I can already feel it," she added. "But I'm going to be OK. We gotta keep pushing. We gotta keep living ... God, I loved him. He was the best."
