Nigella - not sure if your saw my response to you re toilet training, I've copied it below anyway just in case [smile
Your dog can go in the garden, just not into contact with other, unvaccinated dogs.
I actually think that puppy pads make the process of toilet training longer and more confusing for the dog, but understand others may find them useful. Crate training should help, as he shouldn't want to dirty his bed area, which is why you get a crate that has little room for anything other than a bed and maybe water.
You need to be taking your puppy out into the garden basically as often as you possibly can, and certainly after food, sleep, play, about every half an hour at least. Its a pain in the arse at this time of year but the more committed you are early on, I am sure it will reap rewards. Use a command, we use 'wee wee', others use 'potty', or 'be good' etc. When he does go, praise profusely just after the event and/or give him a treat (use some of his food allowance for training initially).
If he does go in the house, just ignore and clean up, pop him outside if you catch him in time.
He will get it, but some dogs get it quickly, others not so quickly, bit like babies smile
Personally, our dog doesn't ask to go into the garden even now, but that suits me, as he does go if I take him into the garden and ask him to toilet.
