Can anyone tell me the best treatment for coccidia in a 4 year old greyhound rescue who, for the third time, has come down with bloody diarrhea. Fecal sample was positive & kennel she was obtained from had treated her with a 5 day course of Sulfatrim on two previous occasions, which has not done the trick.
Your vet might suggest Albon, Tribessen or Corid, but in an adult dog, there is a lot more to getting Coccidiosis than giving a drug. Since the Coccidia can withstand freezing, you have to aggressively treat the dog's home, burn the feces, and clean with 10% ammonia, because most cleaners will not kill it. When did you get your dog? I would have her thoroughly checked out with a complete blood panel, fecal, and urinalysis, to make sure there is no underlying disease process going on, because of the fact that she has had 2 outbreaks already.
It could very well be there is more than just coccidia going on, it may be whats showing up on the slide but there are a number of other things that may not be showing up and are hard to get a positive ID on with a fecal smear such as Giardia, hookworms, and whipworms. These do show up on fecals if you are lucky enough to catch some of the eggs or larvae in a single fecal float. AN infected dog can be floated 30 times before you get a hookworm egg to show up. You might consider asking the vet about metronidazole aka Flagyl along with the Coccidia medecine. I am sure you have wormed her but every 3 weeks for a while with Panacur would be something I would consider incase she has a good case of hooks or whips. A typical deworming program sometimes wont cut it in a bad case of hooks/whips. Also as said before, make sure her envirment is spotlessly clean to prevent reinfestation. If she is a house dog that probably isnt a problem but just something that always needs to be considered.
Honestly, I would treat with a full spread of wormer/antibiotics. I'd do 5 days of Panacur and repeat it 2 weeks later. Do 7 days of Metronidizole (which treats for Giardia as well as other gastrointestinal bacteria) and 7 days of Albon (which is an antibiotic that treats coccidiosis).
Pen- being from the midwest, we deal with coccidia continually. It lives in the soil and is transmitted by birds and wild life. Around my home, on a nice spring day, it sounds like the remake of the Hitchcock movie "Birds"... The only way to avoid encountering coccidia in this part of the country is to keep your dog indoors or only on sanitized concrete. Unless this is the worst case of coccidia known to man I think burning feces and totally disinfecting the house is overkill.
I'm guessing that something else is going on with this dog. If his immune system was healthy he'd be able to fight off a rampant case of coccidia. Coccidia is almost naturally present in every dog's system. Adult dogs usually keep the bacteria to a manageable level where it doesn't cause gastrointestinal upset. In puppies it is common to see coccidia cause upset - but it's largely because their immune systems are immature.
I'd be concerned that you're also dealing with Giardia as well. Unless your vet is actually doing the antigen test they may be missing it on a slide. Giardia usually causes more damage than Coccidia. Again, a dog with a mature, healthy immune system is less apt to pick things up.
Dose him with a full round of meds, get him healthy, and maybe keep him limited to an area you can keep clean and controlled.
