hello people, I'd like some opinions/advice on what to do.
Nori, the lil fella on the picture, is our 1.5y old BC. He used to be very food driven when he was a puppy, then kinda got more and more disinterested in food. He kept a reasonable food drive until about two months ago, when he just stopped caring about food at all.
It isn't like it came out of the blue: We got another BC pup back in january, but they adapted really well to each other. In july I ruptured my ACL and had to stop taking him on walks for some time. Due to taking time off from work, I could spend more time with him and deal with his excess energy through playtime and stuff, so it kinda sorta cancelled out.
About a month and a half ago, his aforementioned younger brother, Tamago, had a mandible fracture (he got his lower jaw stuck on Nori's collar during playtime). He got surgery and the follow-up xrays are looking good, but it's gonna be a few more days until they're cleared to be together again. At the moment, they're having to be kept separate until Tamago's mandible heals fully.
On top of that, we had to switch his kibble a few months back. He was doing ok with it, eating normally. When he stopped eating, we tried switching back to his original one, but that was no bueno.
Now, I'm back to working my regular 40hr work week and nothing we've been trying has worked. I tried making his meals engaging, he loves learning and training new tricks, but not even that has been enough for him to eat. Food toppers kinda work, but do not pique his interest in a meaningful way, he grazes and leaves his food to rot.
I'm at a loss as for what to do. We're trying to wait him out, but it's been a day and a half and he hasn't touched a single meal. He's still drinking water normally and went on two nice walks with me. He's playing as usual. No unusual stool, no vomiting, nothing of the sort.
Now his stomach is RUMBLING and I feel like I'd do anything for him to eat as usual again, it's heartbreaking to see him so intent on starving himself. I don't know if he misses his brother, if he's struggling with the return to our routine, if it's the food... anyways, thanks in advance for any advice or even just words of encouragement. Our life has been hectic and I'm sure it hasn't been easy on him.
