This thread is quite amusing. My working-line Springer is quite content not going out. She would love to, and we will go for a country ramble early tomorrow, but she has her family at home, some exercise and hunting games, sniffs (rural), plenty of cool places, shade, love and attention, and her first doggy ice-cream today.
She likes relaxing in the bell tent with her favourite rock.
We were in the garden at 5 this morning but both decided it was too early and went back to bed. She's being brought up not to work formally, but to be calm, well-mannered, and be a very loved member of the family, so the lack of a predictable walking regime is a useful part of her experience.
She will enjoy going out all the more tomorrow.
I think the thread was to guage thoughts as to walking dogs in the heat of the day, not to judge the nature of, and how much, exercise dogs generally get.
Dogs are all at different stages, breeds, levels of health and fitness, and different family set-ups.
Do what works for you and your dog :)
