I'm currently dog sitting for my daughter. She has a 3 year old working lab. His reason for living is to run and run. He loves chasing balls and once off the lead is super active. He doesn't mooch and sniff he has to dash everywhere. She mentioned this to me so I knew what to expect on the dog field I've been taking him to. Over the past couple of days we've just ambled around the perimeter pretty much because of the heat - well I've ambled he's dashed about. We only stayed 20/30 minutes or so each time because he's panting and panting-today it was cooler so we resumed ball throwing - it takes 15 minutes to get home and we've been back about 20 and he's still panting, thankfully a lot less as we speak. My daughter would think nothing of this but I can't believe this can be good for him. I've had GSDs and terriers all my life and not experienced this sort of activity and after effects.
Anyone got an opinion about this...
Obviously not going to talk to my daughter about it unless people think it's a huge issue.
