Please! this is very important to me and many others. I've owned this dog sense he was 9weeks old. He has just turn 9 years old this past month. This accurance that happened tonight has never happened before. I'm not rich but i would appreciated if someone could help me with any advice as to what might be wrong with him. His name is Duster.. he's very smart.. the smartest dog i've ever had. He is part lab and part chesapeak bay.. however you spell it... please. Earlier tonight he was laying on tha floor ... we have hard wood floors so i don't know if he was just struggling to get up from a deep sleep and pulled a muscle in his left back leg or strained it. But he was floppin around on the floor in appearance to be having a ceasar. The thought ran across our mind that like i said he was just struggling to get up.. but this has never happened before and he acted quick with this flopping. What would be the symptoms of a dog having a ceasar? Is it possible for them to be having a nightmare and wake up exhausted? what should we look for? What kind of home remedie can we look into?
