Nicely angled, mostly.
Here is our latest homework for our canine performance anatomy class. It shows that Samurai is nicely angled in the rear, with a sloping pelvis that means that he can get his hindquarters up underneath him, helping him to jump and turn quickly. His front is straighter, but not bad for a toy breed dog, with a shorter upper arm. It luckily has some angle to it. We'll be learning more about what this all means, but this how things look right now.
