hello. my dog is a 8 month old pit bull. he's very frisky and full of life. always moving. three days ago we redone an old dog house for him. we scraped off old loose paint, replaced carpet with new and replaced only two walls. last night he begin showing signs as if he were "tried". we offered a bone. nothing. he wouldn't move when called. sometimes he'd even ignore us. he likes my daugther and when she was brought outside, he didn't care she was there. this morning he's moved himself from the back fence to the porch steps. please help. what's wrong with kano?
