Hello everyone I have a 16 week old V that is going with us to the river in AZ and the temperature will be about 108degrees F. We live in Southern California and he's used to 80degrees F. My concern is obviously the heat, We are taking his best friend(another active dog)and they can swim and run for hours and hours. We will have a canopy for shade and obviously the water to cool down . Any precautions or advice that anyone could give would be greatly appreciated. BTW he has become a great swimmer. We introduced the pool at 9 weeks and he would just play around in the shallow step but about a week or so ago he jumped all the way in and now we can't keep him out. We are so excited. Thanks in advance for the replies.
