Chewy's medical needs from Javalina attack!

Chewy and I were out for a walk as we do every single morning. We were doing as we do every morning walking along the trails around the park trails. Out of nowhere we were attacked by a javelina family of three adults and four or five tiny babies. One of the larger ones hit me on the side of the leg and I fell to the ground and my dog immediately started to defend and he was attacked several times but he never backed down I got up as the dog held them off while I could get on to my feet and I fired a shot at them and then immediately retreated the area not before I realized my dog was seriously injured by a tusk and his neck was ripped open and his foot is also very injured. I'm in a lot of pain but I have no injuries, only bruising and soreness! I cannot say the same for my poor dog chewy he is very hurt and I do not have the funds for his medical to get him fixed up. We need help to raise the funds to get him desperately needed medical attention. We cannot find anyone that will help with payment plans or anything the only option anyone is giving us is to surrender him to an overcrowded and underfunded Animal Shelter! Please if you can find it in your heart and you're financially able to help out at all we would truly appreciate it and chewy would definitely appreciate it he is in so much pain...Thank You for taking the time to read this.
