Echo needs to go to the vet!

Hi my name is Olivia! I'm reaching out to get help for Echo, a lovely dog who was a stray on someone's porch at first only to be abandoned by animal control on an oilfield site when she had to call them because her neighbor claimed their kids were scared of him. This has to be one of the most emotionally intelligent dogs I've ever seen, and despite only having him less than a week he's developed a strange limp in his hind left leg that really needs to get looked at. I'm also sure he needs all of his vaccines since he's about a year old, and he needs to be neutered. I'm an overnight worker at Walmart and already have two dogs of my own, but I love animals from the bottom of my heart and just want to help wherever I can. If anyone has it in their hearts to help this pup get to a doctor it would be greatly appreciated by the community here since it took almost a whole Community to get him to where he is now. Thank y'all for your time and have a blessed day!

Update! With y'all's help I was able to take him to the vet today and get him his shots done the vet wants to wait on any x-rays on his leg just cuz they might be growing pains. Just thought everyone who has blessed him so far should know how it's going so far! He's opened up a lot since he's started decompressing and he's a super funny playful puppy. Thank you all so much again for even taking the time to read this whole story this poor boy has just had a crazy ride.
