Thank you all for the comments!!
His hips getting so bad happened out of nowhere! He first started limping a little and then before we knew it was was slipping on the hard wood floors in the house. We now have large area rugs all over the house now and he's been getting around well. It's been so hard to see him get this bad, knowing that I only have a year or two left with him makes me sick.
He lives for nothing else in this world but to protect me. I love him so much.

BUT... I try not to think about that all the time, I need to hold tight the time I have left with him!

Sierra is Such a brat! Somethings will never change!
She looks like a rag-a-muffin right now.. she doesn't shed like a Shepherd. She blows coat like the wild crazy wolf girl that she is! When she's done shedding she looks silver.
