Hi Michelle :-)
I have a 6yr old Mal bitch - she is fab and a total character! She has by no means been an easy dog but we wouldn't be without her. She lives happily with my Cavalier & Samoyed (both bitches) although she doesn't much care for other dogs - she used to be ok with them until she was attacked by an off-lead dog. However just recently we have had friends round with their dogs and after an initial grumble she has been fine.
She is extremely friendly with people and loves everyone she meets, she's a big softie and loves attention. Unfortunately she has a condition which means we can no longer take her for walks which is really sad, but when we did, we didn't let her off the lead as her recall was abysmal, she developed selective hearing and if she wanted to go somewhere, there was no stopping her!
She is very strong willed and if she doesn't like something she will let you know. I blame this on my OH training her as a puppy and not giving her enough discipline - she is very intelligent and knows how to get round us!!
I would second Julie and say the worst thing about her is definitely the hair!! She is moulting at the moment and the hoover is constantly out - and we always say in our household that meals just aren't the same without a Malamute hair in them :-D
She also loves to dig and came in yesterday from a particularly amazing digging session - we are currently referring to her as "Coal miner" as that's what she looks like!!
Malakai has pointed you in the right direction for health tests etc....I would definitely say make sure your sister gets her Mal from a reputable breeder as there are some not so good ones out there who are breeding for the wrong reasons. Going to shows is a great idea so she can meet some of these lovely dogs first hand and speak to the breeders and exhibitors - I have found them to be a very friendly and helpful bunch :-)
