okay so this is not the first time that I think this person might be raping my dog. It started because my dog apperantly had diahrea and pooped all over my mom's wooden floor. Everyone was upset, and yelling at him but I said he had never done such a thing, he has never once pooped on my bed. He sleeps with me almost every night, if he needs to pee and I'm asleep he pees by the door, he always has pooped/peed by doors if ppl don't open the door for him, but for him to just do anything other than by a door is out of his character, also he tends to hold it until I wake up. Anyways first time it happened I just couldn't understand, though of what he ate, everything but nothing was out of the ordinary. Then it happens again!!! This time my dog was with me the whole morning and I let him out to do his business he was on the bed, all was fine, then this two people come home, my sis and my dad, my sister came and changed clothes, and then she went out to say hi to my mom, and all I hear is uggh it stinks he did it again, and I heard my mom trying to clean up and all, and telling me I should just leave him outside if he can't control his bladder, but again I stood up for my dog, and I said he has been with me all day and he hasn't done anything if he had diahrea then he would of done it at least once when he was with me. Anyways time passed by, I noticed my dog would have really bad nightmares, he would toss and toss so bad that it scared me. I also noticed that all of a sudden he would follow me everywhere. Even when I would go the restroom, he became really meek, and sometimes would not want to eat anything. Anyways when thinking I though sometimes when I have anal w my partner I get this symptom which made me believe that it could be my dad. Again time passed and he hasn't had diahrea but just yesterday I was eating and realized my dog wasn't with me then I went to look for him and saw my dad in just boxers w a phone coming out of the restroom and he gave me a weird look, I went to my room and saw my dog scooting his butt (he has never done this in front of me) I thought maybe he had to go poop, I got up an tried to go outside, he didn't follow me, I opened the door and showed him I was outside and still he stayed there looking at me, this kept on until finally I got him to come outside. He didn't poop but when I sat down and he was barking at something and had his tail up I realized he had this big red bump right next to his anus, and his anus looked open like he pooped, he didn't have that red bump before. Now today I went to the restroom and I though my dad was asleep on the sofa, I left my dog in my room, but when I came back I quickly checked him and although the swelling has gone down (sine I been applying heating pads every 6 hours) but his anus looked again wide open. I do not want to be thinking this about my dad. I really love my dog, and his behaviour has just changed so much, he used to be really playful, my mom says is because he has gotten old, but there's times he will just go like a corner by himself, and the thought that someone could be harming him just makes me really sad and extremely furious. If your wondering, yes my dad is the only male in the house. Also one time he was gonna take a shower, and he came (My dog was laying between my legs asleep) my dad came and reached for him and I'm like what are you doing, and he was like I'm going to take him a shower, and I don't know why but I literally said, I'm not letting you take him with you. Then he tried getting the other dog which was with my mom but he wanted to stay with my mom so my mom said leave him alone. I really need advice from outsiders, because if I told anyone else from the family they will think I'm crazy.
