He couldn't take it anymore.
He'd been happy to accompany his mistress for an afternoon walk.
He'd wagged his tale and his rear with candid eagerness as they set out into the countryside.
At first, it had been difficult for her to keep up with him as he shot into the woods to hunt down very large game and returned wrapped in panting joy and saliva.
But she just kept going on and on and on, jogging her way into the early evening.
So, little by little, he had lost interest
and enthusiasm
and by the end of their tour, he was lagging with a tongue pining for water and a sorry look in his eyes.
