I posted this like two hours ago.... I'm not sure where it went???
I really don't believe routine wormers have any effect on coccidia or giardia.... Although, I do think one needs to consider resistance of roundworms / hookworms and such with regard to always using the same type of wormer. We mix it up at times....A&M released a study some years back that something like 80% of all dogs have had or are carriers of coccidia with little or no symptoms... As far as giardia, it is a water borne parasite and requires a snap test as opposed to just a routine fecal... Basically, no routine will be perfect... Over the years, we've changed this or that depending on the latest study or med... It can be overwhelming, frustrating, and a real guessing game at times...
So, basically our routine is as follows:
Regular wormer (Fenbendazole): 6 weeks and every two weeks after...Fenbendazole (panacur) is very broad spectrum including giardia.
Routine fecal (conglomerate) at 6 and 12 wks to check specifically for coccidia.
Coccidia:
Marquis to prevent at day 4 then week 2,4,6,8,10,14 (very expensive)
If you have an outbreak, ponazuril will kill the parasite in just a 3 doses or Albon, but must be given for 28 days (the lifecycle) 10 on, 8 off, 10 on.
Giardia:
Water borne parasite, will not be present in normal fecal, must have a snap test done. However, if one dog picks it up, it will spread very quickly via fecal matter to every dog you have and possibly humans or birds. Panacur is an effective treatment (5 days)
