TW: animal disease, blood.
My old small dog got very sick. 2 day she coughs with blood, now she took a walk and her whole mouth was in the blood. She suddenly developed a tumor under her paw and it seems to have grown into her lung. There is no way to take the dog to the vet, and in my small town they can only euthanize it. I have been preparing for this for a long time, but still not ready. She walks by herself normally and looks guiltily at us because of bloodstains. This is very hard for us. Our family member for over 11 years.
Forgive me for writing here, it's a little easier for me to deal with this.
[update] The doctor said to change the diet and look at the state of health, we believe in the best.
