This is actually a 2 in 1 question. My dog is pregnant how long till she delivers, i would say she is about 2 months. Next question (this might sound cruel but i couldn't think of any other option at the time so please no complaints as my dog was seriously hurting my brothers) I brought my dog with me to my brothers house, she is a 3 year old pit (red nose red devil 100%). I am trying to socialize her more with other dogs. I live in a small town and for the last 2 1/2 years i was in school so i walked her when i worked out and she hasn't really been around other animals. Anyways I'm at my brothers house and his dog a chocolate lab female begins growling at my dog and my dog still on a leash lunges at my brothers dog and I am able to stop her before she bites. I back up onto the drive way unaware that his dog can still get to the drive way. He has an unfenced yard and when he brings her outside he puts her on a wire that twist into the ground. Anyways his dog runs up to mine and growls again and my dog sable bites down on his dogs face and WOULD NOT LET GO. I had my brother grab his dog and we tried to split them apart without pulling them away in fear that it would tear his dogs wound. My dog refused to let go so in a last attempt i hit her upside the head and she let go. I immediately put my dog up and we brought his dog to the vet she had to have her lip stitched and was put on antibiotics. My dog is very sweet when it comes to people but when she is around animals whether its male or female unless she is in heat is very aggressive. I will not tolerate her aggressive behavior and anything that will help to rid her of aggressiveness would be greatly appreciated.
