Help for dog at the beach

This dog has been at the beach for at least a week and a half, but he never got close to Sandra until earlier in the week. She noticed that he has a huge tumor coming out of his left side that reach the genital area and he has no testicles either. It's either a tumor or someone shot him or wounded and that may be his intestines coming out of the wound. When she saw him for the first time Sandra saw something reddish at his side but couldn't distinguish what was it. That means he has been at the beach all this time like that, and that obviously bothers him to walk. He is nice and friendly and needs to be rescued. He looks a lot like Laika!
