Deworm不需要那麽頻繁，隻有查到狗狗糞便內有寄生蟲卵時才需要，見內

Deworm有許多副作用，下邊鏈接這篇文章的第二頁說的比較清楚。也就是說在deworm之前，必須先做檢查，有必要才吃藥，否則就不需要

Most veterinarians recommend that adult dogs be dewormed only when there is specific reason to do so, such as when eggs or parasites are found during a fecal examination. Dogs can also be kept on a yearlong heartworm preventive that also protects against many of the intestinal parasites. All dogs should have a fecal examination done at least once a year.

Most dogs carry ascarids as encysted larvae, but intestinal infestation by the adult worm is rare in the healthy dog. Hookworms are likely to be a problem in adults only during periods of stress. Only milbemycin (Interceptor) is effective against encysted hookworm larvae.

所有跟帖： 

• 那就每年夏天6片revolution?副作用小，還防flea. 覺得vet給的這廣譜deworm的藥有點多餘。 -COOOLCANADA- ♀ (0 bytes) () 04/15/2014 postreply 10:15:49

• 狗狗經常出門嗎？出門是否亂吃亂咬？一般防皮毛寄生蟲即可。至少丘丘除了必打的 -Churchill- ♀ (123 bytes) () 04/15/2014 postreply 10:21:59

• 每天出門。什麽是必打的？Frontline是和revolution差不多的？ -COOOLCANADA- ♀ (0 bytes) () 04/15/2014 postreply 10:31:11

• 我自己給丘丘定下的核心疫苗是Canine Distemper和Rabies, -Churchill- ♀ (380 bytes) () 04/15/2014 postreply 11:16:32

• 對，作用是一樣的。我的Vet建議用Frontline，因為其中不含有一種有害成分 -Churchill- ♀ (86 bytes) () 04/15/2014 postreply 11:19:10
