compare how he/she normally behaves to how she/he is behaving now. aggressive barking when unexpected or vicious biting causing blood to come out of the veins or arteries would be aggression. if he/she is showing the whites of his/her eyes when you play with her she is very bored and needs more attention. though that can be a sign of happiness. if you are afraid of your dog consult your vet. i am very passionate to dogs and i would recommend that you don't try to get your dog put down because it is extremely cruel. also, if your vet says you have to have it put down, say "NO, I'LL SEND IT TO A RESCUE HOME" and then do. if you love your dog, which i do, keep it in a safe, detained area until you are happy that the dog has calmed down. never assume a dog is going aggressive because it bites you once, that could just be a love bite or a sign of affection. i hope i helped!
