Ha! Ultra high energy puppy? An OEB does not fit that at all. That is another reason I got one. She is just fine on the lake all day but the next two days she sleeps non stop and likes to stay in her bed or mine.
Even when she was a puppy she was happy being as active as I was and sleeping as long as I did and many times longer. That is what they seem to do best....sleep.
Mine is next to me right now sleeping.
Even with shade, water, and a fan in certain temps that will not be enough. I would not want to be in the woods with a dog that needed special treatment like that. The other two will get jealous when you put the bulldog in the car to suck up some A/C.
