I just thought it was fascinating that two dogs renowned for superb movement and born 8 years apart, are so similar in type. Just as an interesting comparison, check out Rikkor, who was born 8 years after Fanto.
Not so similar . . .
Barb, the visual landmarks for hind angulation are the hip joint, stifle joint, and hock joint. In an appropriately stacked dog, the upper thigh will be vertical and the hock will be vertical. This allows the judge to accurately assess the amount of hind angulation a dog has.
I think the easiest way to explain the difference between Dingo and Fanto’s hind angulation is to look at the angle formed by the lower thigh (bone between the stifle joint and hock joint). See how Fanto’s lower thigh forms an angle slightly different than Dingo’s? Fanto appears to have a slightly lesser degree of angulation between the upper and lower thighs. In the dog world, this is labeled more angulation. For example, a dog with 90 degree hind angulation would be considered to have “more” angulation than a dog with 110 degree hind angulation.
Another thing you could try is to visualize the bottom of the photo as a horizontal plane and compare the distance between each dog’s stifle joint and the ground.
For reference, the SV standard calls for 120 degrees of hind angulation between upper and lower thighs.
Hope this makes sense . . .
