Years ago when we got our rescue bearded collie when training her, I thought she was dumb. I eventually figured out she wasn't. She thought, "But, why?", not "Yes, but ". While a lovely, social, family pet, with her innovative and independent way of thinking, she wasn't going to be a good role model, so I waited till she deceased before getting my puppy.
When I tell Nitro to drop when I'm watching TV in the sitting room, we have an understanding he can choose where, on the rug in the sunlight or the shade, or on the cool tiles. I want him to be comfortable.
When I call Nitro inside and he needs to potty first, he pauses to look at me as if to say, "Hold please, I'll be right there", then hurries off to do his business first.
In July I had been very sick, while very ill he slept on my bed. A few nights ago I happened to cough, once, in bed. Nitro came into the bedroom, gave my face a thorough diagnostic sniff, then hopped on the bed and lay down. I need never suffer alone :-D
