Ivy, in English if a woman says she has a girl it means that she is a mother and her child is female. It would be better to say "I have a female dog...". Dogs are wonderful. They love their owners if the owners are good to them. They even know when you are sad and they always try to make you feel better. Some dogs are better friends than some people. You are lucky to have such a good dog. 

I have a female dog, her name is Perla, but we had 2 dogs, the another died, he was a male called Coke.

My cat likes dogs. I tolerate them. 

four? oh U must be very happy with them :))))

I love dogs. Today I have four , but I 've had more dogs previously

They give love to you without asking anything in return :))))
