Hello, I'm Dr. Deb and will do my best to help you today.
I can understand your concern if Abby has internal parasites since the nursing puppies may be at risk for picking them up, too.
Can you describe the worms that you're seeing? Are they long, like spaghetti?
Or are they short and look like dried rice or coconut?
There may be a slight delay after I receive your answers since I have to type up a response to you. Thanks for your patience. Deb
It sounds as if she may have tape worms, then, as opposed to round worms which are long and round, like spaghetti.
Fortunately, these parasites can't be transmitted to the puppies and the wormer used to treat them will be safe to give her even though the puppies are still nursing. The drug which I like to use is called Praziquantel (aka Droncit although it does go by other names) and is available at most pet/grain stores. The dosage amount to give is indicated on the label based on the body weight of the patient.
In most cases, these parasites are transmitted by either a blood meal from a flea (which could have been some months ago) or by ingesting rodents such as mice or chipmunks (a fairly common way for cats to get them). What's known as an "intermediate host"...the flea or mouse...is needed to complete the life cycle which is why the puppies are not at risk for getting tapeworms from Abby.
Typically, only one treatment is needed in case you were wondering.
I hope this helps. Deb
