Query: only way to hike with dogs

I have two of these Gulpy's and when we go hiking at a county park a few miles from my home I carry one and give my dogs a chance to drink every 15 minutes or so. They drink from the plastic trough like they normally would a bowl and I squeeze the bottle to speed the water going into the trough, as they drink quickly. I keep the second in the car in a small cooler for them to cool down when the hike ius over. This is the best way I have found to keep the 3 of them hydrated in warm or any temperature, for that matter.
