Hot weather and sleeping
My almost 6 month old puppy has been sleeping a lot lately. He is eating as usual (each day hungrier haha) and plays for a really long time every night (He plays the same way, but he has been more enthusiastic about his ball than before, and he used to be quite enthusiastic already), he is also going to three or four clases per week (group classes), each of goes from 1 hour to 2 hours. But the weather has been crazy so, his classes get re scheduled or suspended sometimes. Temperature has been going from 110 to 130 Fahrenheit, and it has been raining at least twice or three times a week. He does spend most of his time inside the house mainly in the hours with that temperature, but then again, he does go outside for potty (he is smart and avoids going outside from 12 to 5).
But he has been sleeping a lot lately, like a lot. Sometimes we do not notice he is in the room, until you open a bag of chips (no matter the bag he always things bag noise is food). This started like 4 days ago, I think. We have not been to the vet, because he went there for a check up a week and a half ago, and his stools are better than ever, he eats as good as he always has, he is still quite vocal, but behaving much better, he controls his barking a little more, and he starting to walk better on leash....
But I do not know, may be I am overthinking it, Could he be depressed? Can it still be the fact that he is still loosing some teeth? or the fact that he is growing? or is it probably the really hot days we have had lately?
