How awful Bright. I hope your old dog getting cancer (so sorry) was a coincidence, cause my son always wanted a dog so after my ex left, we got an older rescue dog and use that same tick and flea stuff Job uses on her cat, that you put on the back of their necks. They cannot lick it off. I hope neither of our dogs or Job's cat gets cancer. That's really scary.
Anyway Bright, ticks do carry diseases both people and dogs can get. Like Lymes disease, that is can really strike any body system and can cause arthritis and headaches and confusion. Your poor dog. Maybe it needs dog antibiotics. Does a holistic veterinarian prescribe antibiotics if needed?
