Canine nosebleed, losing nasal tissue?

Q:Hi all

I have an Aussie Shepard (blue healer) abt 14 years old, was doing really well until about 6 mos ago, got a bit slower.

Well 3 mos ago there was a minor nosebleed incident while in the car, stopped he walked around and was fine;

its been now 2 weeks? at home, lying on the carpet, relaxed and started nosebleed. I heard an odd sound and looked over to find him licking his nose and saw the blood.

one nostril only.

there have been almost 10 bleeding episodes now? first thought it was a cut nose from dogfood can. nope. on the 2nd one called the vet, got tested for rat poison, turned out negative, nothing wrong with the blood clotting at all, liver relatiely okay, white cell count high, and thyroid very low.

but years ago it was low and he was on T4 about 6 years?

Vet then said he needed to get tissue biopsy sample in the nose and use endoscope. thats the day he took the blood initially, but that night on the bleeding episode, he had something coming out the nose, tissue of some kind.

this tissue looked about the size of an earthworm, 2-3 inches and 1/4 inch diameter or less. I would start to help pull the tissue out the nose, it wouldnt come out, caused pain.

eventually the dog sneezes, spraying blood everywhere, and this earthworm looking tissue is on the floor (put lots of papers down). took that in for the sample, sent it out, results from the lab were negative for cancer, it was nasal tissue. different vet filling in the other days Id never met before

So my question is about how to cure this. what could come out the nose like that? why is the nose shredding up that way? this afternoon he was already weak and had a long episode. couldnt sit up in the car much later, couldnt sit up to eat dinner, barely walked in, back legs giving out.

for some reason, he lost muscle mass in the back legs

worms?

so Im cleaning his back end because (it was necessary) and notice worms?

call the vet. hey, worms in his back end. are they small, white, rice size things wiggling? yes. okay thats a tapeworm the vet receptionist? said. okay get the medicine, Ill come over and get it.

see the vet, droncit? take all 4 tablets b/c the dog is 50lbs or so. take all 4 at once.

ok

next day, had to clean his behind again, still lots of worms? the night before he was really agitated, couldnt sit, couldnt stand.

I clean the worms, and notice hey, whats that? a hole in the skin near the tail? and zillions of those worms coming in/out. I clean it and the hair is falling off. a small pencil sized hole in the skin in a few places.

so I cleaned as much as possible and called the vet. receptionist said thats normal, the worms are in process of dying from the medication. but they are coming out the skin, is that normal? just a second Ill put you on hold.... the vet says come in at 12. (1 hour)

they were fly eggs/maggots, how gross. poor dog. so we cleaned that up, shaved his fur in the back area, to the skin in several parts, now its red and inflamed 2 days later

so far in 1? week he has had:
new prescription of T4 thyroid, seems to have helped
new set of vitamin K ? pills
took the 4 droncit pills for the misdiagnosed tapeworm he didnt have
new prescription of antibiotics
and 1 chewable drug to kill the fly egg parasites

because he was bleeding in the house and I had to work out of town? those here in the house must have locked the dog outside in the day, where the flies bit him. it would be 5 days or less from fly eggs to wormlike larvae?

I have to work out of town next week also, dont know what to do.

well the dog has another appointment tomorrow Sun at 430pm pst with the other vet office. any ideas or suggestions are helpful as to why the nasal bleeding, and why tissue comes out like that

thanks in advance!
