Hi. I have a 6 year old Irish Terrier (40lbs) He is having a dental on Friday. His ALP was 1000,All other levels are normalALT,AST,GGT He has no symptoms , no diarhea, no vomiting, no over drinking or eating nothing. Very active especially on walks. Can stress cause a rise in the ALP levels? Can boredom/inactivity, separation anxiety be a factor to stress. Also can topical flea medication "advantage" be one also. Since my son started school he doesn't get out as much so he is alone about 9 hours a day 4 days a week we have a walker for wednesdays but none yet for the other days. I've started taking him on walks when I get home instead of just letting him in the yard which is very large (35,000 sq.ft) and fenced in. He really enjoys the walks. He just doesn't have any symptoms of Cushing's.
