Disclaimer, my girlfriend and I have been together for two years, I’ve lived with her for a year. She has Dysautonomia, or POTS, and got him for the sake of training him to be her service animal. He is extremely smart, 6 months old, but he is a rescue. He is a chocolate lab, and we believe he is mixed with pit. He has a ton of energy, and of course teething as he’s a puppy, and labs are mouthy, we have taken all of that into account. She got him around august, and in September I had to quarantine for two weeks due to thinking I had covid. During those two weeks he slept in my spot in the bed bc my gf felt bad telling him to go to the bottom of the bed if the space was empty (she loves dogs over humans.) before this, he was kind, he never hurt me. After I came out of quarantine he began to bite me, not like, I wanna hurt you, but like hard enough to hurt me, I’m anemic so I bruise easily, he has broken skin on many occasions, but once I leave our bedroom he gets calm. At night he pushes us apart and sleeps on my pillow with his head right next to hers. He bites me if I attempt to move him. We haven’t spent time together since September and both have depression and we give each other serotonin so not being able to see each other Is affecting our relationship, she has tried to discipline him, I have tried, her mother has tried. He doesn’t go to training until nov 11, but that’s only for a week. If anyone knows anything that will help, PLEASE LET ME KNOW. he does not respond to being locked in his kennel for 10/15 mins when he’s mean, he doesn’t respond to me yiping when he hurts me, he doesn’t respond to no, he does not care. He has issues listening and I’m at my wits end, I don’t want to move into a separate bedroom but that’s where things are headed rn. He has proven time and time again that he does not respect me.
