Plantigrade foot occurs normally in humans in static postures of standing and sitting. It should also occur normally in gait (walking). Hypertonicity , spasticity , clonus , limited range of motion, abnormal flexion neural pattern, and a plantar flexor (calf) muscle contracture, as well as some forms of footwear such as high heeled shoes may ...
No treatment is known, but most dogs retain the ability to walk and it is painless. [7] Diabetes neuropathy is more common in cats than dogs. It is caused in part by prolonged hyperglycemia (high blood sugar) and results in dysfunction of one or both tibial nerves and a plantigrade stance (down on the hocks).
[15] [16] The dog's paw similarly contains bones arranged in a semi-vertical orientation. In the human and the elephant, the column orientation of the foot complex is replaced in humans by a plantigrade orientation, and in elephants by a semi-plantigrade alignment of the hind limb foot structure.

The fully erect stance is not necessarily the "most-evolved" stance; evidence suggests that crocodilians evolved a semi-erect stance in their forelimbs from ancestors with fully erect stance as a result of adapting to a mostly aquatic lifestyle, [5] though their hindlimbs are still held fully erect.
Digitigrades include birds (what many see as bird's knees are actually ankles), cats, dogs, and many other mammals, but not plantigrades (such as humans) or unguligrades (such as horses). Digitigrades generally move more quickly than other animals. Comparison of lower limb structure. From left to right: plantigrade, digitigrade and unguligrade.
Other symptoms in both cats and dogs include ataxia, asthenia, hepatomegaly, visceromegaly, enlargement of head and distal extremities, heart murmur, degenerative atrophy, thickening of skin and fur, stridor and a plantigrade stance in cats.
'From Puppy To Dog' is a subreddit with 72,000 members where folks are posting side-by-side pictures of their pets now vs. when they were still little.The photos are so cute and they come with an ...
Both species bore a passing or superficial resemblance to a very small, dog-sized saber-toothed cat. Machaeroides could be distinguished from actual saber-toothed cats by their more-elongated skulls, and their plantigrade stance.
