1. Yashbans is supposed to be good. I have not bought a dog from them but have used them for some import paper work and was charged a huge amount and the goods were not delivered as promised and in the end had to use my own contacts. Its the daughter of the main lady who first started the kennel, I dealt with. So please see the dogs before buying them, even though they may sound very good on the phone or talk very well.
2. Do not leave the pup for too long in the pen and introduce it slowly to it. Use it for feeding etc so the pups associates it with good things otherwise he/she will hate it. When away, I somehow feel safer when a pup is locked in a crate if ever I have to leave it in it. Pups are generally very naughty and find ways of coming out of pens, so be careful and try it out first before actually leaving the pup and going out of the house.
