Aj is your dog on medication or anything at the moment, if he isnt there is a lot that can be done.
Did u say that your family was away as well, i know it sounds silly but he might have just been missing them, dogs are like that. There could be loads of reasons he was a bit dull, so if u are worried just give your vets a ring.

I stopped going when i grew up and didnt really pay much attention to religion but recently while going thru bad times i found it again.
