Here is the quick story: My wife watched a friends 6 month old Chihuahua (which is the brother of her puppy) last Thurs thru Mon. We received a call from the friend that her puppy was sick, and her vet said it was parvo. I took my wifes two puppies this morning to our vet, and both were neg for parvo, and were checked for Coccidosis. It was neg, but their was not enough sample to really trust the test, but it seems reasonable, because of the symptoms, that they either have coccodosis & giardiasis, and treatment was started for both. My guess is the vet misdiagnosed parvo with the friends puppy????? I have around 30 chickens of different breeds. Because its summer my birds are in tractors and hutches, but they free range almost daily. I have not noticed any coccodosis symptoms with any of my birds i.e. their droppings seem normal and they are behaving normally. My original thought was my birds must be carriers, and the stress of the new puppy got the puppies sick??? But dose this make sense? I understand that coccidosis is extremely common, (it is around all of us thru other birds, flies, roaches, etc..) but I think it unlikely that all of my birds would be carriers, and not see any signs of sick birds? Either way, I am going to try to get some sample tested over the weekend. My Question is: I am planning on going ahead and treat for cocc to be safe. What has worked for you? And, as I guess it matters since it is so common, if my tests do come back positive, and I treat, should I just assume my birds will always be carriers? Thanks for any help! Coccidosis is just cunfusing.
