Help Save Rex !

Hello ,

 My dog Rex is a loving and caring pup , he is sweet loving guy who love his tennis ball and his foam sticks. On May 3rd all of that left him as he became different, he wasn’t the puppy. He had became sad and unhappy. We couldn’t find him as he had lied down under a bush and we couldn’t find him until the next day, when we had took him to the Vet Hospital. He is still there today as of May 7th and this is where we need your help. I’m hopping from small job to small job and have money saved up but not enough. So please anything helps. Thank you !
