Thank you all so much for the advice. I will definately take all of it into consideration. We are planning to take him to have him weighed on thursday, so I am going to try to get an appointment with the vet then. I hope it's something that can be corrected easily. When he was 6 months old he had a surgery to have two non malignant tumors removed from his head, one was on top and one was behind his ear and I worried like crazy. I love my Goliath, wish me luck.
