people have pups run them on hard ground and wonder why they jack or aint got nothing left mid season... then blame the dog, I blame the owner, we all make mistakes but surely its common sense... heat plays a big factor 2, burn a dog out in this hot weather. I wont even walk my dogs till 9pm every night when its like this just not worth it... I see people walking pet dogs at 3pm in the day lately, tounge hanging right out, don't think its just lads with working dogs the majority of dog owners aint got a clue...
