Help our family dog, Frodo

On March 1st my daughter took our corgi, Frodo for a walk- just like she does everyday. From inside, I heard my daughter screaming and crying. "They're attacking Frodo!!!" Frodo saw a woman walking her two labs and like any other dog he got excited and in the spur of the moment my daughter was unable to take control of the leash and he got free. These two dogs then attacked him. I ran out, but was unable to do anything as I had my infant in my arms. All I could do is scream as I saw my dog on his back being brutally bitten by these 2 labs. My boyfriend had to pull one of the dogs off because the lady could not control not one of them. Frodo finally broke free once and as he got to his feet from his back he was then jumped again. The two other dogs sustained no injuries as they had Frodo pinned down and unable to defend his little body.  We took Frodo to the vet right away in critical condition. Having extensive bleeding on his chest and left leg. He had to stay overnight for surgery, sutures, blood work and had drains put in. His chest is very bruised and has internal damage to his trachia and ribs. He is in a lot of pain right now and may need more surgery. Frodo is three and a half years old, we have had him since he was 2 months old. He is the nicest dog you will ever meet. He loves people and would never hurt anyone, person or animal. He's not just a pet, he is our family. He means the world to us. Frodo is in a lot of pain with life threatening injuries. Our family is just so heartbroken and devastated to know that he may not make it through this tragedy. My daughter is inconsolable. Because I am a stay at home mom, we are struggling profusely and in urgent need to come up with the funds to keep him in our lives. He has so many good years left in him. We will be forever grateful to whoever can help. No matter how small, any amount is greatly appreciated. The funds will go directly towards Frodo's medical bills including pain medication and antibiotics. Thank you so much for your support.
