american accents tend to pronounce the words clearer than british - also british accents change a lot from region whilst there are regional american accents I find the differences not as strong. So I think american is easier.

yes this sounds perfectly fine to me :) Although if I was talking about my dog I would probably refer to the dog by it's gender. So for example if someone asked me; Who are you going to give your dog to? I would say: I'm going to give HER to Jane. If it is already known that the subject is a dog it would not be necessary to repeat the word dog. Otherwise yes that sentence is good.
