Fur

In spite of hogging the bed, stealing the sheets and passing gas in my face, I do have best dogs in the world. 
Garrett and Cole saved up their Milkbones and bought me this for my birthday:

A custom made dog carrier. It even has a little tailgate!  Some assembly was required, alas, without opposable  thumbs, the dogs aren't able to work a wrench.  However, they do excel at providing moral support.

On Wednesday, they escorted me to the vet school.  It's always an epic battle to get the dairy cow in the trailer.  The dogs, realizing my fatigue, offered 3 extra sets of eyes for drive the hour drive to town.  Especially appreciated is their assistance when I check the location of my 38' trailer's butt and all I can see are dog heads blocking my view of the mirrors. Bless their hearts.
The equine residents at the farm are also very capable of contributing to my mental health.  Some provide you with a struggle at first...

... simply to make victory that much sweeter.

As the animals here can't unionize, we're aspiring to get them to do all the work, so we can lay around on the job.

For now though, they still excel at being support staff.

Cole and Garrett are much too daft to be trusted around tractors, so they guarded the fort while Pete and I dug our post hole.

New auger tip wasn't a match, requiring an hour of grinding and fabricating to make it work.  Then, the auger, which had been left partially disassembled, was reassembled, almost causing me to stroke out.  
Thanks to my canine companion, I kept my cool and we finished around 8 PM.
Wishing you the kind of unfatigable, unwavering camaraderie I get 24/7.
