2+ week old pup. fine at rest, while being held, etc. - when the pup is up walking, very shaky, like tremors. Motor function is fine( compared with siblings), no trouble traveling or climbing. But very shaky whle in motion. Seems I saw this once before in a friend's litter . They held that pup back he gradually improved by about 10 weeks of age.
Pup is otherwise very healthy and has shown no other symptoms.
Anyone seen this before? Vets- ideas? .....
