Can anyone suggest how long it should take a dog (in my case a 5 month old beagle) to be fully house trained.

we have had him for nearly 2 weeks and originally started using the puppy pads but decided to teach him to go outside straight away. when we take him outside he does his wees and poos but sometimes he just starts to wee in the house without any warning. he never whimpers or makes a sound to tell us he needs a wee and when he sits at the door and we think he's telling us he needs a wee outside when we let him out he doesn't go for one. I know it takes time and perserverance and that his bladder is still being educated to know how to hold it in, but I would like to know anyones thoughts or experiences on timescales for being fully housetrained - ie if it should take less than 2 weeks then maybe we need to see what we are doing wrong - or if it takes longer than 2 weeks then it will just be a case of perserverance and consistency in how we are currently training him.
