Is this normal?

[Bienes Raices]

Tenants paid, got the keys etc. today. They told me they want to paint one of the rooms in the house, make one alteration, and bring a dog (but they'd told me before that they weren't bringing any pets because of allergies). They don't own the dog yet, someone else they know has it and can't take care of it.
(Obviously I'm not going to say yes to all this stuff--I told them "I'd think about it and get back to them"). I was a bit surprised at being hit with all of this stuff at once. Is asking for all of this stuff the norm.
