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

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

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

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

Hello,
first, I think toi should ask them why they don't want a another dog. Then, toi will find arguments against their opinion and explain to them why do toi want one dog. But are toi sure toi can take care of a dog with your studies? It's a good idea toi had (take care of your dog during one week) but can toi do it everyday with two dogs? I have three chiens and i l’amour 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 toi will be in your own flat ou house, toi will be able to have every pets toi want so don't be too sad if they still disagree.. Good luck!!

i will help
