Hypertrophic osteodystrophy


Recommended Posts

In looking at all the info on the web the longest lived was 2 yr 8 mo.

 

I sure hope they're wrong wrt Jack but.....Dobbin I posted the link with TNS info and there are other links in it. It's a death sentence and I really hope your vets figure out what is wrong with Jack.

Positive? From the little research I was able to do Tibbie was born maybe around 98. I sure hope I'm wrong but that means she was 12 when your Jack was born......

 

I think the Tibbie you have found is a great grandmother to Jack's mother Tibbie. That is what it looks like in the pedigree information we have.

Is "Sportingfield Hollowshot Jen" in your info on Tibbie. All that I have found indicates AU/NZ breeding top and bottom mixed.

 

The most obvious question though is what about Jacks littermates? Does he have any? And how are they? Have you spoken with their owners?

I thought TNS pups don't survive very long? Is 18 months outside the norm? Or have a misunderstood the disease? ISTM that when we have these discussions the claim has been made that pups don't survive long and so TNS may be missed because of such early losses?

 

J.

I think my point in discussions here has been that there seems to be a lot of variability in presentations. So some affected pups might die in utero, some in early infancy (as my affected pups would have), some might die due to vaccine reactions before developing other signs, some are the classical sickly ferret-faced 8-12 week old pups, and some will survive until early adulthood.

 

Our specialist vets (with experience with other TNS cases) didn't think our older pup met the criteria for TNS, because his neutrophils weren't trapped, they did migrate to areas of infection (ie lungs). Possibly it depends on the timing of testing in the cyclic pattern of the disease?

 

Anyway, no, I haven't been saying previously that ALL affected pups die very early, just that presentations can vary significantly and not necessarily fit the "usual picture", and so some cases are likely to be overlooked completely or attributed to other causes.

Journey, if you check Anadune, you'll find Jack's pedigree. H. Mill Reef is there (with lots of Aust/NZ show lines) and while I can't see Hollowshot Tibbie (the old, ISDS Tibbie is Tibbie at Hollowshot), her mother H. Miss Tique is listed and she's half Aust show lines. So it's no mystery, there are known TNS carriers on both sides of the pedigree.

 

Dobbin may not have access to the details of Jack's littermates, so it's probably up to the breeder to contact them. If he were TNS affected, each pup in the litter would have had a 25% chance of being affected and a 75% chance of being unaffected, so it's entirely possible that they are all fine. I would be interested to hear if any of them had died though, and their apparent cause of death, if you ever hear, Dobbin.

 

Hope Jack is having an okay day today.

If we are dealing with TNS with Jack, it has definitely been overlooked. Many of the symptoms of HOD mimic those of TNS.

 

Right now Jack is back to 'normal.' This is the way it always is. He is sick with a fever and other symptoms for 3-5 days and then He is back to his border collie ways. He will probably get sick again in 3-5 weeks (even on antibiotics and steroids).

 

We will keep everyone posted when we find out more about Jack's condition and what the breeder finds out.

Yeah, that's what we had with our TNS pups, although it started when they were tiny, presumed to be the unlucky runts who didn't get adequate colostrum for a novice mum. They also had a bad reaction to vaccinations (big lumps at the site). While they initially recovered completely, by the time they were 4monthish they hadn't recovered from the last issue before the new one struck, and were starting to look a bit worse for wear. It tended to be different things each time, so first it was 'gastro', with diarrhoea, then a respiratory infection, then a swollen joint and lameness, etc.

 

It was about 4 week cycles, from memory, and I was initially looking at cyclic neutropenia (gray collie syndrome) as a possible cause- it's usually shorter cycles, 10-12 days. There's a gene test for this in Collies, but I'm not sure if it is related to TNS.

 

I found this article interesting:

UK 'Grey Collie'

It was diagnosed as cyclic neutropenia in a farm-bred UK smooth coat border collie, but since she had three week cycles rather than the usual short GCS cycles, I wonder if it was TNS. She survived for almost 3 years.

I am a rookie when it comes to pedigrees and such. I am a suburban Border Collie owner! I do know that we do not have Jack's paperwork because we have not got Jack fixed. He has been too sick. He is from Hollowshot Border Collies in Hastings, Ontario, Canada. The breeder is now waiting for results for the TNS tests. She will know in 2 weeks.

Hello.... I was reading your string of posts..... we received a border collie from Hollowshot in Ontario. Did you ever find out from her the results of the tests? I am sorry to hear of your loss. Our border collie came with parvo. The breeder never did reply back to us once she found out our little gal had it.

Our border collie pup was just diagnosed with this . He is 13 weeks old. I see This thread was quite awhile ago. How are your dogs doing now. We just got our dog back after 3 days in urgent care . He is heavily medicated and can’t stand on his own. I’m so heartbroken at the moment so I’m just looking for some hopeful news
