Hey maryellen,
I think TF is a good adjunct treatment to boost the immune system, yes. I usually use homeopathy, tailored to the individual, to cure my HW cases, few as they've been over the years. It works, but it takes hiring a homeopathic vet to pull it off.
Ancillary support comes in the form of a heart glandular made for dogs and yes, transfer factor.
They are usually negative in 6 months.
