I notice that sometimes when Thor is standing, his front legs will shake and sometimes I've seen his back leg shake especially after retrieving. Is this something I should really be concerned about? :-\
Does it only happen during high drive situations like retrieving. If so, I would thinks it all adrenaline. Blood can really get pumping sometimes. If it happens when the dog is not active and has a high heart rate - then it could be something else.
I guess sometimes it is DURING retrieves. :-\ For example, I noticed it when we were outside and came back inside and he had a sip of water. While he was drinking it was shaking. But then, sometimes I've noticed it when we're in the car and he's just sitting back there and his front leg starts shaking.
Is it the same thing for humans if the way we're sitting causes our legs to shake sometimes?
