I am so sad;(((

when i was walking up a hiking trail with my mom i heard a dog cry! i looked around and didnt notice aything at first, but then i saw a little dog tail behind a arbusto, bush siguiente to the fence! i walked over and saw her head stuck in the fence she was bleeding too! i called my mom over and then we took her head out carfully and took her to the vet! the vet told us that if we wouldnt of found her she probably would have died! i started to cry really bad! she is okay now! But i only get to keep for 2 weeks then i am going to have to give her to the shelter



how can i convince my mom to keep her?
