what is wrong with my dog?
I have a 10 month puppy he has all hes shot, he became acting weird today when i got home, he seems weak, ears are down like hes scared & runny nose, when we tries to sleep he will get up randomly & just stare at nothing for about a minute then lay down & do it over, i dont know if this has anything to do with it but about a week ago he would wake up at night & start hacking but nothing would come out this lasted only 2 days.
