Help me bring home my pup!

Hi, my name is Mauricio, I've just turned 12, and I'm from Peru. Last year Melquiades came into my life, and we have been best friends ever since. Melquiades is my Jack Russell Terrier puppy. This year my mum won a scholarship for a Ph.D. in Cambridge. My family is my mum, my pets and me, and the plan was to make the trip together. She did her best to make it possible for Melquiades to travel with us from Peru to England, but the paperwork was expensive and did not arrive in time. We had to come without him. It has been four months now, and I miss him very much. In February Melquiades had pica, and he needed a surgical intervention as his stomach was obstructed. He is fully recovered now, and it we need financial help for getting him here with an specialized agency. Migrating has not been easy for us. Please help me to be with my beautiful dog Melquiades again so we can feel more at home. I can keep updating about the process until he gets here :) Thank you.
