Yes, I understand that well! Having a dog is really good for the soul.
But an old dog in particular costs more money, perhaps it needs special food, becomes chronically ill, or has pain. And what do you do if you have to do military service? Who can take the dog then? I love anyone who is willing to adopt a dog because this topic is very close to my heart. Nevertheless, you have to be willing and able to commit to something for several years, in terms of time, money and society. I am incredibly sorry that things are difficult in your country, it is a catastrophe for generations of traumatized people. I really hope you find a way out!!
Maybe you can share a dog with someone else? Are there people around you with a dog? Maybe you can help another person with his dog, in my case I am searching for someone, who can care for my dog on some weekends. That would be really helpful for me, more then you can imagine. Maybe this is something you can do in your town? I know, it's not exactly the same, but being with a dog can be helpful!
