Surgery for Callie’s broken leg

My name is Callie I’m a baby cane corso I’m 4 months old and loved more than anyone so yesterday I decided to give my mum the fright of her life and run of in a dark field and hop a little wall and fall funny on my elbow for me to end up with a lateral condyle fracture of my left front leg my mums only options are to put me to sleep as they won’t remove my leg as I’m going to be too big they said to only have 3 legs and I really don’t think that’s fair as I’ve only just began to enjoy my life and I love trying to eat my sisters cat on a regular basis lol please can you help my mummy pay for my surgery

thank you
