Hey!
I was just feeling like updating.
A few days ago my dog started shivering hard 24/7, she was always sleeping on the bed and no matter what we tried to do, she didn't move and was seriously depressed.
She didn't eat&drink for around 30 hours, so we gave her some salami and put on it some water so she won't get dry. it took several tries until she started eating it as well.
She barely poop/pee. she didn't want to go outside, we made her go outside once a day to poop and pee..
She just didn't do anything, she had similar symptoms to humans depression+anxiety symptoms. we thought maybe she broke something or she is in pain, so we went to the veterinarian who completely checked her and said - there's nothing wrong with her. the veterinarian said that if she keeps acting the same for the next 2 days, we need to do further checking. thankfully she slowly got through it and after more than 24 hours she started being normal and full of energies again.
My whole family was so worried about her because we hate when she's sick. it might sound a bit weird to you but you won't know the feeling until you have a pet for a while.
Anyway, she's good now and here is a photo I took on our garden after the "depression" she went through.
