Good questions
What is Coccidia?
A tiny parasite that lives in the gut and causes watery stool. It is especially common in puppies and kittens, and it spreads through infected stool.
ToltraBoss or CARE?
ToltraBoss is for Coccidia only. If the stool test also found Giardia, or you are not sure, CARE treats both in one bottle.
How long is a course?
Once a day for 3 days. Always follow the label on your bottle.
How do I stop it coming back?
Pick up stool straight away, wash bedding and bowls, and keep the area dry. The eggs survive in yards and bedding.
When should I call the vet?
If there is blood in the stool, your pet is vomiting, very tired or not drinking, or a very young puppy or kitten has diarrhea.
