There should be no pain upon a normal range of flexion and extension of all limb joints. \n* Palpate the muscles for atrophy, masses or pain. Palpate the joints for thickening/heat/swelling.\n* Muscle tone should be examined at the same time as joint mobility [2]. \n* Examine the digits and skin of footpads or erythema or cracking.\n "},{"_id":"5a898bff24ffcccbb1000039","treeId":"5a570e2221b7ca3842000029","seq":3544654,"position":1,"parentId":"5a675d3542e9c9f473000038","content":"### Dogs\n* Comfortable range of motion can be determined by gently moving the head.\nDorsal range - Lift head with support to look at the ceiling. \nVentral range - Tuck head to touch pectorals. \n* Move head laterally on both right and left sides until almost parallel with the thorax to assess lateral motion. \n* Limb assessment and weight bearing should be done standing.

Assess for any enlargement. \n* The popliteal lymph nodes sit between the belly of the gastrognemius muscle. Do not confuse for the ventral fat pad. The popliteal lymph nodes are more discrete and firmer. \n* Examine the mammary glands and determine if any masses.
