Thank you- that may be where we went wrong years ago- puppy pads everywhere and it took ages to actually get him house trainedThat's because puppy pads teach a dog the exact opposite of what you want them to learn - that going outdoors is the only place to go :-) A puppy pad tells them it's ok to go indoors. I wrote the following for someone else but have copied and pasted it here in case it is of use to you.
"Toilet training for puppies.
First and foremost you need to set your dog up to succeed by giving it every opportunity to be able to go outside at regular intervals.
I always put mine on a lead to take them out as the blowing leaves, waving grass, shiny stones etc. are way too much of a distraction. I take them out after waking, training, playing and feeding (but at least once every hour when they are first learning) and also look for any sign that they need to go out – circling and sniffing being good examples.
You have to go outside with them – leaving the door open for them to come and go as they please is not training them – yes there will be times when they toilet outside because they just happened to be out in the garden when they needed to go but you need to be there with them to reward them for going and the odd time when they do go without you there is pure luck, but you have lost the consistency by not being there to praise them . When they are actually going I praise them and use a marker word for the action of going to toilet – I use the word “Busy” but any word will do. The second they have finished (not before because you don’t want to interrupt them and risk them stopping) I then reward them straight away. Once they have learnt to associate the marker word with the action – i.e Good Busy” I can start to use the word earlier as they are performing and then treat when they have finished. Once the connection with the word and the action is firmly entrenched I can then start to use the word as a command – so Busy means time to go outside and toilet. My dogs will now go outside to toilet on command because they know exactly what I am asking them to do – makes life so much easier if they can go before I go out or before a car journey etc.
If you use puppy pads then my advice would be to ditch them entirely – the puppy pads are telling them it is okay to go indoors when , in fact, you want them to never go indoors but always go outside. Being patient and being consistent is the key.
If they do go indoors don’t make a big deal of it – clean it up with a biological washing powder solution and just make sure that you give them those regular opportunities. "
