Pet Sitter in Modesto, California

I have 3 chihuahua dogs, I treat them like my own family. I walk them 3 times a day. I make sure they have food water daily. I don't have experince taking care someone pet, i'm sure i will take care of them the same way as i take care of my dogs. I see pets outside running around i want to help them to but i don't know if there's on owner..(for example we went vacation in Las Vegas there's a loose dog running around in the street I told my parents please stop let me make sure his safe, cause the dog was causing traffic.and if i see a person hitting there pet i feel anger inside me cause it's like there hitting there child......that's how much i would love to take care animals...give me a chance
