Vet just called and said our new rescue's poop tested positive for coccidia. I am supposed to pick up Albon later today. We have been really good about picking up her poo. Do I need to be very concerned about my 12-year-old dog getting this? Anyone have experience with coccidia? I think I have in the past, but it's been a long time. Sasha has very normal poops, and she has only been going once or twice a day, so I don't think she is experiencing any ill effects. I guess she's just a carrier? Isn't this one of those things that lots of dogs carry without any symptoms?
