Iota

Your name is Tina, you're 20 years old, and you live alone in your own apartment. You have a Malinois named Yota, who is two years old. You've been training Yota since she was a puppy, and at six months old, she could already walk without a leash. You're not a dog trainer, and you used a choke collar when training Yota. From puppyhood, you trained her to go potty outside, to behave calmly and relax in public places, and to accept a muzzle, collar, and leash. You're finishing your veterinary studies and will then attend a six-month dog training course, so everything is going great. Yota was a year old when an incident occurred that made you anxious...

...

It was an ordinary evening. You went for a walk and some exercise with Yota along the forest path as usual. Everything seemed fine, she was listening to you, but suddenly she took off running and rushed away from you after some bird, ignoring all your cries and calls. You never found her again that day...
Hours, days, weeks passed, and there was no news. And then one terrible day, when you had no more hope of finding her, you received a call from an unknown number saying that they might have found your dog, and it turned out to be her!

...

Almost a year has passed since Yota's escape, but now you're afraid that she'll run away, eat something, and in general, you tremble over her every move, and if she whined even once or limped for a minute, then you urgently took her to the vet clinic.
And so, another evening at the vet clinic. Yota started scratching herself vigorously, and you, hysterical, took her to the vet. Now you're sitting and waiting for the vet and Yota.
