This is what worries me, the smell. I admit I'm not fond of dogs mainly the smell I'm very sensitive to smells living with a smoker. I know for a fact she will not walk it everyday let alone for an hour.
My friend owns a staffie and it **** all over their house and raids the bins everywhere it's a complete mess. As soon as you walk in the house the smell hits you and the dog is all over you, you end up straight into the shower when you get home. I have to wear a beanie hat and a long sleeve shirt everytime I go downstairs so I don't smell of smoke, I don't wanna smell like dog too.
To be fair - about the dog smell/mess etc... my mum has 2 dogs: bedlington terrier cross and a whippet terrier cross. Because she cleans dog bedding, hoovers dog hair every day, does not allow the animals upstairs, walks them both at least twice a day (probably 1-2 hours in total), is the boss of them

Your mum sounds like the exact opposite of a good dog owner.
