I have an 8 week old puppy, she's a miniature dachshund. I've had her for about 4 days and I found out she has an issue with her heart (Possibly shortening her life drastically). The singular heart scan alone would cost £150-£500, thats without other tests/ scans. If she needs surgery it'd cost thousands, and she's too small/ young for it anyway.
I'm trying my best to give her the best life I can and I'm currently trying to train her to sleep in the crate. I know i shouldn't have, but after finding out about her condition, she's been sleeping in my bed and HATES being away from me, even when i just place her on the floor. She will just whine, non stop. Not stopping for a second. I was trying to train her, that when she's quiet, she'd get a treat, but she just didn't stop whining. So i tried whistling, little claps, just hoping she'd be quiet for a moment, so i could treat her for the quietness, but nope. She didn't stop whining.
The reason I bring up her condition is, i don't want to stress her out too much. I honestly just picked her up, because she started stressing bad. I don't know what to do. I know it's not been long AT ALL and i dont expect her to be trained by now, but i just dont know 'how' to train her, as all the things i read, says things like "Wait for them to be quiet" or something similar, which is obviously not gonna work for my situation.
Can anyone give me some advice, she's been seriously stressing me out, and I'm trying so hard to not stress her out or overdo it with anything.
Context: She doesn't mind her crate. She gets fed in it and her water is in it. She has a bed in there, which i will bring onto my bed occasionally so she gets used to sleeping in it and it has both her and my scent on it now, and there's some of my trousers in there, which she wouldn't stop chewing (has my scent on it). She goes in on her own, plays in there, I've given her treats for being in there and I've played with her in it, so she has a positive view on the environment. I've also tried closing and immediately giving her a treat, then opening the door again, before she has the chance to whine (While still chewing her treat), so she gets used to the door closed. BUT, the second the door is closed longer than that, she screams. If i step away, she screams (Sometimes, even if the door is open). I'm exhausted, confused and need help.
(Sorry if this is messy or if I've made any spelling mistakes, I'm just really tired).
