Lilly is a four-month-old Labrador mix puppy in Dallas, TX, who needs $500 for emergency hospitalization.

When the phone rings at Pooch Savers Rescue, they never know what emergency will be on the other line. And their latest call resulted in the nonprofit organization taking in a pup fighting for her life.

"We were contacted by a woman who claimed she found a pup and couldn't keep her," Scott B., from the rescue, tells Waggle. "Then she said the pup was throwing up and had diarrhea. We immediately had her bring the dog to a veterinarian that we paid for."

The pup, now called Lilly, tested positive for Parvo. A potentially fatal virus that is preventable with a vaccine. "My heart just sunk," Scott says. "There's no cure or medication for Parvo. All you can give is supportive care. It's so inexpensive to get a dog vaccinated. That's what is so frustrating to us."

The rescue transferred Lilly to the Veterinary Emergency Group. Her best chance for survival was to be hospitalized 24/7. Now she's in a fight for her life.

"If there had been a delay starting her treatment, it could have been much worse," Scott adds. "They put a feeding tube in just in case things went South. We are very worried. It just makes you sick."

Lilly's round-the-clock care will run up a tab costing thousands of dollars. Pooch Savers hope pet lovers out there will help them come to Lilly's rescue by giving to her fundraising campaign.

"If there's a chance a dog can be saved, we'll go the extra mile," Scott says. "She is a four-month-old puppy. We needed to pull out all the stops. We want to say a big thank you to anyone who donates!"
