We lost the big guy 2 weeks ago...a 14yo Malamute mix. Per the vet's age/weight ratio chart, Bart's age was the equivalent of 115 human years. When he was younger, all the vets said he wouldn't last much past 8. At the end he was down to 110lbs. In his heyday, he was 140lbs of muscle. We've had him since our daughter was in 6th grade. She's 25 now. I still see his big butt out of the corner of my eye and hear his old man bark in the distance.
Fortunately, we still have the little girl...a 2yo Lab.
