How long can she hold it?

[TainaPR]

Now im 100% sure this has been asked many times but Im on my mobile phone and cant search for the answer. How long can a puppy hold it? Ive bought Taina a kennel and what I hope to be the last pack of puppy pads so I can start teaching her to go outdoors. She's 'supposed' to be 5 and a half months (byb breeder were not sure of her real age) but im guessing shes around 4 and a half months. Thanks!
