Follow the usual protocol.
For whatever reason these past couple yrs I have known so many dogs with HW. Until then never knew any.
They followed the advice of their vets and all dog are back to normal. It’s a long treatment that can cause discomfort, but it’s a situation where you have to weight the risk/reward. Suffering with the disease will be much more uncomfortable.
Personally I would go with what is known to work and ask the vet how to alleviate any discomfort from side effects.
As for future prevention ask your vet about NOT giving a monthly preventative and opting for fecal testing every 3-4 months. That way your senior dog isn’t being fed pesticides/antiparacitics when she doesn’t need it.
You are great for adopting an older dog. And one with an illness not less. I wish you many years of health & joy with her.
