Hi there! We live in Raleigh, NC where currently the high is around 97 degrees during the day. Our 9 month old (110 lb) berner, Barkley, is always inside where it's cool, however, we like to take him for walks in the evening and plan on taking him to the beach this summer. So, I'm thinking of getting hair cut really short but some people have said that their coats actually provide some insullation which helps cool them. He has beautiful hair so I want to make sure it will grow back the same after I cut it. Any feedback on whether or not cut his hair short would be greatly appreciated. Thanks!!
