With a man, I doubt you can change his mind- however- maybe once he realizes this tosses out calm home arrivals- and the need to exercise the puppy and the work involved- either he will say " I can do this," or " uh maybe later.."
And keep in mind- this constant activity level is the main reason I do not have shepherds anymore. Do I still drool over a great looking shepherd? YOU BETTER BELIEVE! Do I love to talk about shepherds?? YOU BETTER BELIEVE IT! Would I own one again- I hate to tell you.. no..
