welcome to the forum, and ditto the others, take some deep breaths, you haven't had him for very long.
jump our back yard fence, cowers when we approach him, submissive pees, and generally shows no interest in warming up to us. Once we carry him down the stairs and into the house and into the office he's happy to lay at our feet. But then wont move from what ever spot we put him in.
sounds to me like he is actually shutting down (learned helplessness) he doesn't know that he has any other options so he lays in one spot. it is a fear response. though we know that you and your boyfriend are trying to help him, it will take quite a bit of time for you to convince him of it.
the first thing i would recommend doing is giving cody a "safe" space to be in. a little used room like an extra bathroom or something along those lines, or an x-pen in a corner could work for this, in the space you will want to make your life easier by covering the floor with paper or pads so that when he does go, it will be easier to clean up. you will also want to put a crate, preferably a covered one with a bed inside, and a bowl of water as well as some toys and chewies... this will be cody's "base" his space to go to "escape" and his place to be when you cannot supervise/interact with him.
keep all of your interactions short, and low key, speak softly, move slowly, don't look directly at him or stand fully facing him. use his meals to your advantage. toss his kibble to him at whatever distance he needs to be in order to eat it... and slowly decrease the distance, but alwasy moving at his pace.
over time he will associate you and your BF with good things, and he will start to warm up to you.
i would highly recommend one of these:
and you might find this thread helpful https://www.dogforum.com/dog-behavior...signals-10084/
again, use calming signals to your advantage, first, respect them ie if the dog is doing them, you might need to stop/back up what you are doing until he is comfy, second you can mimic them ie a nice, obvious yawn and head turn when you approach might let him know that you mean no harm, third you can reward the dog for them, when you see him trying to come toward you, but stopping to sniff the ground, you can toss him some of his meal and let him know that calming himself is a good thing.
another vid that might help you
counter conditioning is a term you should start getting familiar with. it is very likely that your dog will need quite a bit of it
when dogs are afraid/uncomfortable they go into fight or flight mode, from the sounds of it, your dog is tending toward "flight", but the principles of CC apply to either, so even though the dog in this video is in "fight" mode, he is still reacting to fear. are you familiar with clicker training? this is another tool that you will find helpful in dealing with a fearful dog.
you are not alone. my dog behaved similarly to yours when i brought him home. it takes time, patience, and compassion, but IMO and IME it is well worth the reward of building that bond with your dog. good luck, and we are here for advice and support 100% free webcam site! | Awesome chicks and it is absolutely free! | Watch free live sex cam - easy as 1-2-3
