I don't want to look after my dog
What makes you not want to take care of your dog?
There's so many reasons! For starters, he's stubborn and he doesn't respect me.
Remember, you picked your pet, and they did not pick you. It's your responsibility to take care of them and feed them. Have them put in a shelter or let someone adopt them if you're going to be irresponsible to them.
It's fine. I'll give them to some stranger, who probably deserve me more. I honestly would rather not have a dog.
You took on the responsibility for it when you adopted your dog. But if you really need to give it up, please make sure it goes to a good home and not a random stranger on the internet.
