Why does my dog always shakes his head when it house or outside like something is on him
I have a Chihuahua JRT mixed how do I train him since both breeds are hyper dogs? he's always shaking his head like something is on him. and does not eat his food, I give him Purina One puppy food. he's 6 months old. loves to run around the room in circles. Should I get him spaded now? He is a loving dog but follows me everywhere, he is potty trained and knows when he wants to go out. Another thing is I take him out so much cause he will not go on puppy pads.
