“I (18f) live with my parents 38f and 42m. When I was 17 I bought a dog named spud (with their permission) and my parents have decided that they think spud needs another dog to keep him more entertained.”
Well, the new dog is her parents’ idea, and OP was a bit skeptical at first because she has sacrificed a big part of her social life. She simply didn’t know if she wanted more commitment.
And her parents made it even more difficult by asking her to sacrifice even more.
“However, they have said if we want the new dog, they would have to give up their holiday (which has not been booked nor paid for) to look after it, while I would have to give up the two concerts I have paid for and had booked for 3 months.”
OP is already overwhelmed because she works and drives her brother to school and back. These concerts were her vents.
Read the full story below:
OP asks:

OP is a teen girl living with her parents. She has a dog, which she bought with their permission

The parents decided that Spud (the dog) needs company. They would give up their holiday for a new dog, and want OP to give up two concerts she was eagerly awaiting

OP wasn’t thrilled with the idea. She already has a poor social life

Parents call OP selfish and insist she makes sacrifices to get a dog she didn’t even ask for.

People who want the dog should take on the responsibilities and sacrifices

Do they really need a second dog?

OP thinks another dog is a good idea, but not now

Redditors mostly say this:

Maybe OP should reconsider her priorities

This is a valid question :

OP is not thinking clearly about the future

Dogs cost a lot. Looks like OP didn’t take that into consideration

If you don’t have anyone to help you out, taking care of two dogs means missing a lot

This experienced Redditor is right:

The bottom line is: Think where are you going to be in five or ten years, not where you are now.

This teen asks: “Am I being selfish?” We don’t think so.
She didn’t ask for a second dog; it was her parents’ idea. It would hurt her social life so much, and on top of that, her parents ask her to make sacrifices. What for?
For OP, it is a lose-lose situation. No wonder she is so frustrated.
We hope the family will come to their senses. Social life is incredibly important to people, especially teens.
OP deserves to have one.
