My previous Shepherd, Shane, always knew when I was sick and would try and cuddle, be very attentive and loving, even as a puppy. However, Chance, is not like that. He seems to be the opposite when I am sick. He is now 15 months old and am wondering if this is inherited behaviour or if he will learn as he gets older to pick up on this. He wants to guard, but will not calm down when I am sick,(ie. sitting on me while I am in bed trying to sleep and sitting straight up and barking at anything outside) I end up having to put him in his crate or I get no rest. Is that his way of taking care of me? and if it is, how do I get him to be a little more gentle? We have no other behaviour issues.
