Not read the rest of this thread .... just your post .... so you may already have been given this advice (BTW good luck with your new friend). Imo you should ditch the choke chain asap (and buy an easyleader or similar). They are about £10 and worth their weight in gold .......... extremely effective, the animal will very quickly get used to it, and it is kind to the dog/bitch ..... no neck pressure and instant control. I use them to train young labs and have recommended them to many other dog owners (including a neighbour that re-homed an Alsatian) and without exception they have all been very impressed. You should be able to pick them up at any good pet centre/vets.
