I say that my dog doesn't usually like strangers even though she does.
Why do you tell people that your dog doesn't like strangers.
I don't want to have to talk them and it could be very tiring for her.
Dog's are so much fun, but you shouldn't lie to people about your dog just because you don't want to talk to them. Try being a little bit more friendly.
I don't know why she likes everyone. I just want to go on walks without being bothered.
Others might get the wrong impression of your dog if you keep telling them that they are not friendly. Don't you want your dog  to make some friends as well. If you let others socialize with you for just a little bit, it might not only cheer up your dog, but you as well.
