Hello all - little Aldo is now 12 weeks old and doing fine. The biting is easing up a little bit, but he sometimes still turns into a maniac. He is now sleeping through the night though! Since we got him at 8 weeks, we've noticed that there are times when his front legs will shake when in a sitting position. Has anyone ever experienced this?? At first I thought it was just normal and that it would go away by now, but it has not. I'm reading all kinds of crazy stuff on the internet about this - all kinds of ideas - low calcium, lyme disease, vitamin deficiency, etc. He is eating very good quality food. He also has two small (about 3/4 inch) bumps or lesions on him - one on his hind leg and the other on his front shoulder. At first I thought something may have bit him, but now not sure. Each area has gotten bigger with some hair falling out at the site. I never saw anything on him (like a tick) and these just kinda showed up one day. It's been about a week and they are not getting better. Any thoughts would be appreciated.
