How do I ask my mom and dad for a new dog????

I have no idea what research Ты did, but I can already guarantee Ты that guinea pigs are not еще expensive than a dog. They're Еда alone is cheaper than dog food.

Also, did Ты ever stop and think the reason your parents are saying no is because Ты haven't been taking care of your dog very long, and Ты constantly keep changing your mind? That's great that Ты took care of your dog for a whole week, but what happens when Ты get tired of doing that? What happens when, Далее month, Ты want something else?

Ты want to convince your parents? Show them Ты actually want this. Take care of your dog, every day, for a month, two months, six months, a year. Then tell them Ты want another dog.

Hello,
first, I think Ты should ask them why they don't want a another dog. Then, Ты will find arguments against their opinion and explain to them why do Ты want one dog. But are Ты sure Ты can take care of a dog with your studies? It's a good idea Ты had (take care of your dog during one week) but can Ты do it everyday with two dogs? I have three Собаки and i Любовь them. We fortunately have a big garden. My medical studies take up all my time soI can't see them in the year.
The best solution is to ask to your parents a dog for your birthday.
When Ты will be in your own flat или house, Ты will be able to have every pets Ты want so don't be too sad if they still disagree.. Good luck!!

i will help
