You can get gov grants to open an animal sanctuary, with a 501c3 however, you must have experience with animal training and caring for the animals properly. You can be a service dog trainer. Or a K9 Police officer. Or have a bomb sniffing dog or a dog that works as a service dog looking for illegal stuff. I would love doing that. I think you would get great enjoyment and have a bond with your special dog. Or a kennel attendant, horses etc. Not much of a great living however, very rewarding. It depends on how much effort that you put into what you want to do. Another great idea is to open a pet shop.My sisters children all boys open a reptile shop in San Diego and they did well with that for awhile. So many paths that you can consider with animals. Saving, rescue, foster, placments, working as an animal control officer at the ASPCA a no kill shelter. Going out and saving animals, that would be great. Or you could assist in surgery the Vet assistant in surgery, a vet tech with surgery expertise pays a bit more than just a receptionist, or a handler. A handler is good too. There is always a great need for people who want to work with animals. I hope that you find your way. I wish you the very best in whatever you choose in life.
