It may be hard to believe but both these young sisters are both type 1 diabetics.
Even though they're only 8 and 10 years old, they check their blood sugar levels multiple times a day with adult precision.
McKenzie and Thalia Moreno are among the overwhelming number of children in the United States that live with the disease.
8-year-old Thalia was diagnosed first back in 2006 followed by her older sister McKenzie in 2009.
"It's overwhelming, it's emotional. When the first one was diagnosed it was really hard. I get emotional just thinking about it," said Mckenna Moreno.
"Nothing we did caused it, nothing could have prevented it, it just happened," continued Moreno.
If left unattended, Type 1 diabetes can lead to serious complications and even death.
That's why they Moreno family has their eye set on a potentially life changing diabetes alert dog.
The dog is trained to smell when the girl's blood sugar level changes, but the dogs are expensive costing up to $20,000.
With the help of fundraising, and an organization called Guardian Angel Service Dogs, the Moreno's hope they can live with peace of mind.
