Jasper - got at 12 weeks - born and raised in breeders house and spent a week elsewhere - was quite sound sensitive (but that could have been a learned experience from my other dog at the time).

Tassle - raised (maybe dragged might be a better word) up in a house with 3 young kids - got her at 5 weeks - the kids had been treating them like dolls till that point. She HATES other dogs - but adores children!

Siren - In the house till 5 weeks - then a kennel, I got her just under 7 weeks - very well adjusted and pretty bomb proof

Zeff.....well - only 13 weeks and had him a week - bit soon to tell
