Hello, I am new here, and i come from germany so excuse my bad english please. I learned english at school. Where i was told a dog is a neuter (in grammar). If you have a dog girl named Kaya (like mine) do you say "My dogs name is Kaya, she loves to play with the ball" or is it the right way to say: "My dogs name is Kaya, it loves to play with the ball"? I hope you can help me about this. greetz Caschyra
