I'm a food nazi, and as of late my dog is a sausage shaped atrocity. She and I are getting back into shape when I get home.
I used to be a foot nazi. Actually, just more of a grooming fiend. No joke, I would literally go nuts if feet and nails were not trimmed, coats were not clean and tangle-free, and there was no staining of any sort on any white parts.
Now that I have no high-velocity dryer, no dog bathtub, no grooming shears and no dremel? I'm decidedly less anal about grooming my own dog. If she's clean, doesn't stink and her feet have been trimmed in the past month, I'm not going to flip out.
Being a service dog handler has changed my "things" quite dramatically. My real "thing" with my particular dog is her behavior, and the behavior of myself and other people around her. I strive to keep her in a certain state of mind - calm, focused, aware of her surroundings but detached enough to not get riled up by them. My dog is a border collie and is high strung and rather prone to anxiety by nature, so at times it can be quite a challenge. I get frustrated with people who deliberately, after being warned not to, screw with this. I can't control environmental things that might bother my dog, like construction or thunder, but I can control your **** hand reaching for her, or your **** face making kissy noises.
Oh, I have another thing. I hate hate hate off leash dogs that aren't trained to RECALL or DOWN immediately. Too many times I have to deal with the stress my dog feels when an offlead dog decides the recall can wait the 30 seconds it'll take to molest my dog and leave her wound up tighter than a tick.
