terrible news for my 7 months old male shih tzu.. he has TICKS!! what am i to do??..its been about three weeks and i still can't clear out the situation. I've bath him everyday w/ tick and flea shampoo, however it doesn't clean out the ticks completely. After I shower him, my mother and I would look for the ticks and we kill them, but that doesn't seem to work either. IT KEEPS COMING BACK!! we shaved him hoping it would help get rid of the ticks but that also didn't work.. I don't know what to do

My dog doesn't have any bit that cause him to bleed, however there are certain pink dots, i believe it a bit from the ticks.. ANY SUGGESTIONS?? pls help
