Hi there :)
Mals can keep growing (and do) for quite a while, they are a slow maturing breed. The height range for a Malamute bitch is 58-66 cms ( 23-26 inches)
Bitches should not be bred from until at least 2 years of age though ....plus you will need to have her hip scored as well as eye tested.
Can I ask, did your breeder not put endorsements on the pedigree? ALL good breeders endorse pups so they can assess the bitch before she is used for breeding. This way, hopefully, bad examples of the breed won't be bred from :)
If I can help at all you can email me Melodysk@f2s.com :)
