I have a question. My Dobie is almost two tears old now but the last couple days has been acting different. Normally he is a very hyper active dog but lately he has been strangly calm. He just wants to be right by us and sit on our feet. Kind of like he is just being super protective and his job is to stay right by our sides. At first I thought he was sick but he has been eating normal and not in any kind of pain. Is this a normal thing or has anyone experience anything similar? Dont get me wrong I dont miss being mobbed at the door when I get home but he just seems he is sad and not his normal playful happy go lucky self. Any comment thought or advice would be greatly appreciated.
