Most are total sofa potatos by the time they are a year old.
They are fine for older person. In fact the majority of afghan owners are over fourty, kids out of the house and retired. They love to lay on the couch with you. Puppies can be a hand full but many breeders have older puppies and they tend to start calming down around six months. A run or two a week in an enclosed place and they are happy dogs.
Grooming can be work, but a maintained coat is an easy coat. If you alter them, most of the time I recomend you shave them down. Altered afghans revert to puppy coat and that can be meserable when long. If you want a full coat, dont alter the dog and you wont have a horrible time maintaing it.
There are some temperment problems in hte breed. Normally the dogs are spazes. If the dogs barked nonstop at everyhting they saw, they might have been fearful. B ut lack of socilization can do it as well. They are pretty terratorial as a breed and I can just see an unsocilized terratorial afghan being a big pain in hte butt.
When I say they are spazes I mean afghans with poor temperments.
Remember the breed was a rather multi purpose dog that roamed with nomadic tribes. Most afghans that have regular excercise are not prone to running off and never coming home. In fact the majority always come home in a bit once they are done whatever they felt the need to do.
As for books. The last real afghan book was writen in the eighties or so. Look for the Afghan Hound, used bookstores are good places. Most of the books discus the history and the bloodlines and stuff, frnakly there isent anything about living day to day life with afghan hounds. Its good to find some and meet them and hopefully find someone to hang around their house with.
Most people that meet them have a diffrent idea of them then they did before the meet them. They are a rather effecent dog and easy to live with, the hair is just a crowning glory. Its only as nice as it is becuase we obsessivly work at growing it. Remember, a full afghan coat takes about three years to really come in. They are not born in full glory.
I figured it would be a while till their coats came in. Like my huskies it takes over a year for their coats to become fluffy and three years till they stop growing. :) I know Novia is going to be a big ol' fuzz butt LOL
