But yesterday the bad breath drooling and licking are back. Not as bad as it has been.
She didnt eat last night.mainly laid on the couch sleeping with us. Its not uncommon for her to sleep all day,she was never a very active energetic dog. Its not uncommon for her to not eat at night plus she had a pretty big breakfast yesterday.
There is a channel on Telegram called "Fenbendazole and Ivermectin". Lots of people post their questions and experiences there. You might find helpful info there with a search on the channel just using the word "dog". The Joe Tippens video (he had tumors in his neck) is readily findable there. There's a youtube video there that has a vet talking about Fenben: "Cancer in Dogs and Cats: Top 5 Natural Remedies" with Dr. Andrew Jones. He's saying 3 days on the fenben and 4 days off. I didn't watch the whole thing because I don't have time at the moment, but it's at about the 2 min 45 sec mark on the video which is only 8 min 17 seconds.
