Dog Bites and Bee Stings

I asked my mother if, while watching my sister’s dog, I had to spend time with the four-legged friend or just feed her and walk her. She texted me that just feeding and walking is perfectly fine. She added “I don’t think they have a concept of time.” That made me chuckle and wonder, well…do dogs know about time? Will the mutt be sad that I left her alone for too long and made her feel lonely? Will she be looking at her dog watch and rolling her dog eyes? It doesn’t matter. I was relieved of my duties so the dog can be lonely without me.
