I've had my baby since about December 20th of 2017 . Recently he has been very distant. He sleeps more than usual, barks and gets spooked a lot more && all around just doesn't seem like himself . He doesn't seem bonded with me like he used to be and I'm really worried about him, I just don't have the extra money to go to the vet (considering there in not one close by me able to see him) if there is nothing wrong with him ??
