Sure he is ok and I don't need to do anything. This started three days ago. I noticed him sleeping a bit during the day, I thought well it's hot, they have plenty of shade. Their coupe and run is under 4 80 years old oaks. So they are ok. We keep plenty of water and cool treats for them. But he was sleeping a bit that night my husband woke up to let the dog out at 3am and he was fully awake and carring on. We weren't sure if it was because of my dog and my husband. So this past two days he has been doing mostly nothing but sleeping. He looks healthy, he gets up to take a drink and to eat. No issues with potting and or any body parts. He looks otherwise healhty. He has found himself one spot that he has kind of wallowed out in order to lay in and he is just sleeping a lot. Is this normal or is there something I should be looking for?
