Late last night he was going bonkers in his xpen. See when he wasn't hurt he loved his pen only if we would leave the door open for him. So with the door closed last night he was going bonkers and jumping up and down. I took himout several times to just sit with him. He tried walking and I noticed him putting pressure on the leg. NO crying whatsoever. He even decided to make a dash and chase the cat but we grabbed him.
This morning he was crying to use the bathroom and didn't want to go on the wee wee pad so I took him out to potty. He walked fine on the leg. He does stop intermittently and pick it up and he is limping. NO crying. He wanted to take off running on me but I recongized the mischevious grin on his face and grabbed him.
I am leaning on it being the sprain. I know we palpated it and saw no signs of a dislocation and he didn't cry at all with the palpation.
UGGGG. I feel so sad for him. Thanks so much for the replies. They have been helping to ease my mind some.
