I’ve had my dog for about 13 years. Someone was leaving him in a graveyard because they couldn’t keep him—they have big dogs, and they feared their dogs would harm him. At that time, I wasn’t able to have a dog, so I tried to find him a home, but it never worked out. I almost got kicked out, and I didn’t know what to do. After much back and forth, I was finally able to keep him. He’s been through both good and bad times. In recent months, he has had trouble walking. He lays down most of the day and sometimes cries as if something is bothering him. I asked a friend, and he suggested that maybe it’s time to put him to sleep. I don’t want to do that, but at the same time, I don’t want him to be in pain. How do you know when it’s time to let him go? ( the pic is a few years ago, he’s such a baby♥️)
