Welcoming pets into your home can be wonderful, but it is not the right choice for everyone and should be thought about carefully.
But one woman who does not wish to let a dog in her flat has been left in a difficult position after her pet-owning sister asked to move in.
While the obvious solution would be finding separate accommodation, she says her pregnant sister has nowhere else to go.
Deciding she was unwilling to compromise, the woman told her sister she couldn't move in unless she rehomed her pooch - and it is safe to say her decision did not go down well.

Taking to Reddit's Am I The A**hole forum the 25-year-old woman explained that her older sister wanted to move in after breaking up with her boyfriend.
She wrote: "The problem is she can't find a place to rent because of financial issues and breed restrictions (her dog is a pit) and that's why she wants to move in with me (I own my home)."
While she said she loves her sister and wants to be there for her nephew when he is born, she won't change her mind about the dog.
"Her dog is neurotic and chews through EVERYTHING. Kennels, doors, drywall etc," the woman explained. She claimed the animal had even caused "thousands worth of damage" at her sister's previous home.
Unable to afford repairs, and knowing her sister could not pay, the woman put her foot down.
But it sounds as if her sister struggled to understand her reasoning, calling the homeowner "cruel" and claiming she was "risking her baby's health by making her stress".
Another family member also begged the post's writer to take in the dog, telling her he couldn't be rehomed "because of his issues and breed.
But defending herself, she said: "I would love to help her and have her keep her dog and I know it sounds selfish but I just bought this house and I really don't have a lot of money..."
Hundreds of people responded to the post, with many agreeing the woman hadn't done anything wrong.
One person wrote: "It's a sad situation but you don't want your stuff destroyed. It's not like you are going to her house and taking her dog, she wants a favour from you, which comes with conditions so you don't end up paying for that favour."
Another thought: "NTA. Your house your rules. If she can't respect that then she'll have to find somewhere else."
And a third added: "I understand your sister's dog is her responsibility. But you have set a very reasonable boundary and for good reason. Please be firm about this. Welcoming your pregnant sister into your studio home is already incredibly generous."
