Thanks everyone! Yes Shilo is a big girl...she's bigger than Nebo. She weighs about 90-100 lbs, Nebo is around 60-65 lbs. Shilo is built differently, her head is much larger than Nebo's, and just overall she is a bigger dog, she just has shorter legs so they are about the same height. We think she might have another breed back in her line somewhere, I don't think she's 100% siberian, she's definitely mostly husky though.
