I am not experienced in this exact problem and in no way suggest you follow my advice , its just what I went through and experienced myself 1 time with 2 dogs

I had Poeple saying not enough calcium etc with a very fast Bitch , 18.60 old Richmond
19 flat bulli then every time up to 400 + she would collapse

In the end I stopped racing her coz I couldnt watch it and tried everything , heres what I tried

1. EXTERNAL LINK
2. Euro carb tablet
3. Bi-carb soda powder
4. Carprofen tablet , both tabs are inflammatories to keep muscles and urinery tracks clean and relaxed
These are administered after the run . If you use a kidney flush before or close to a run , she will have no nutrients in the dog to perform and repair itself . It is 2 days after the run

Blood tests full and viewed by a GREYHOUND vet ! A normal vet wont have the understanding of the greyhound breed and their numbers !

This was step one above

Nothing came back from tests and it still occurred , I gave up on her after months of tinkering this around a bit and in the end , instead of caging her up in kennel , I now leave her out all day to work as she wants and I took her off everything including kibble ( due to salt ) and shes as good as ever and never had a drama again , mind u I never trialed her again on track !

Another dog I had similar issues with was a dog called big benno 40kg dog

The routine I used for him was a shot into muscle of Aminoplex 1.5 ml / tripart 1 ml combo ( a vet use will do double this when water diabetes occurs ) 3 days before race it swabs 48 hours

Then after he ran same day I would do the same shot with also a euro carb tab , bi- soda teaspoon and carprofen tab 1 in his feed that night
Carprofen tab again with euro tab next day

Kidney flush every 14 days

Benno performed lovely and was upbeat under these procedures

These are the best rehydraters in the game after runs and trials . Throw away all your other recharging powders , they are a waste and will do more harm to kidneys then good

I use coconut water / lectade mix at track 50/50

After hard race runs when they put in an uninterrupted flying run I mix up the isotonic mix and put over meal ,most wont drink it on its own . Caution with ratio , i find 20 :1 perfect mixing in litre portions or small teaspoon to large cup mixed with kettle hot water . It will swab ! Its only for use over 2 days after race ! I leave 5 day gap for race .

Advice , besides above info is see your closest greyhound vet first but with full bloods and disclose everything you do in your routine as it will help him diagnose !

He will agree with all other procedures Ive said

Good luck robynne, its heartbreaking I know

I didnt divulge my full diet as I dont think the iron and methionine are a direct result of the underlying issue , to be fair most trainers already have this in place and I know of many GRP trainers who dont use it also for no drama

I believe there is an issue there , wether its just genetics you have to work around with the methods I suggested or with luck you might find an issue with the bloods or a urine test .

I dont believe an iron and methionine is the only problem as my extra methods contain these minerals also .

Im not a vet but , we both could be wrong

Worst part is I can almost guarantee the sires initials are MB or SP

Yup. Wish I knew sooner !!!

Thank you, mine are fed a primarily BARF diet. Very little kibble 50 grams a day at most.

Thank you Nathan for that information.
I've also tried a lot of things and am still tinkering. Will look at what you have said. I already use Coconut Water and Lectade.

Blood results
Test Result Alert Units Reference Range

*SODIUM 152 mmol/L 144 - 154
*POTASSIUM 5.6 mmol/L 3.9 - 5.9
*CHLORIDE 112 mmol/L 105 - 117
*BICARBONATE 19 mmol/L 15 - 29

*NA:K RATIO 27.1 26.0 - 35.0
*ANION GAP 26.6 mmol/L 13.0 - 29.0
*GLUCOSE, FL.OX 4.2 mmol/L 3.3 - 6.8
*GLUCOSE, SERUM 0.0 Low mmol/L 3.3 - 6.8
A glucose result obtained from a plain serum clot tube
has the potential to provide a falsely lowered result
due to ongoing consumption of glucose in such tubes.
The result obtained from a Fluoride Oxalate tube will
be a more accurate estimation of the true glucose
value.
*UREA 8.6 mmol/L 4.5 - 11.2
*CREATININE 0.17 mmol/L 0.09 - 0.17
*SDMA 13 ug/dL 0 - 14
SDMA is a marker of glomerular filtration rate to help
evaluate kidney function. It increases earlier than
creatinine in some animals with chronic kidney
disease. Unlike creatinine, SDMA is not impacted by
lean body mass. SDMA and creatinine should be
interpreted together, along with a complete
urinalysis.

Both SDMA and creatinine are within the reference
interval which indicates kidney function is likely
good. However, if SDMA and/or creatinine is
approaching the upper end of the reference interval,
early kidney disease cannot be ruled out.

Note: In puppies,the SDMA reference interval is 0 - 16
ug/dL. In Greyhounds (adult and puppies) the SDMA
reference interval is 0-19 ug/dL. SDMA and creatinine
results should always be interpreted in light of body
condition, urinalysis and other findings of kidney
disease.

*LIPASE (DGGR) 21 IU/L 0 - 250
*MAGNESIUM 1.2 High mmol/L 0.6 - 1.0
*GAMMA GT 4 IU/L 0 - 9
*SAMPLE APPEARANCE Moderate haemolysis
This amount of haemolysis may falsely decrease T4,
ALP, L-ALP, Bilirubin, Glucose and SDMA; may falsely
increase Protein, Albumin, AST and K ; and may affect
other tests (such as GGT) in an unpredictable manner.

In vitro haemolysis is more common in sick patients,
when clinical factors can make RBCs more fragile.
Haemolysis can be minimised by using an appropriate
sized needle, avoiding excess negative pressure during
blood collection, gentle mixing and handling of tubes
after collection. For biochemistry, centrifugation
after allowing the sample to clot is ideal with prompt
removal of serum or plasma from the packed red cells
if using a plain tube; if you use a serum separator
gel tube (gold top) no further

I can't copy straight from the results for some reason.

Please be aware these results were AFTER the first seizure.

These were taken straight after the first seizure, which was Jan 2023. The bitch that had a seizure this week I am just resting. I'm so disappointed that dogs can have this and be allowed to go to stud ( I just found out he had a seizure when racing ) yes obviously I didn't do "enough" homework but I only got to have one litter from my bitch and now I won't breed from her pups. People really suck.

Thank you I've dealt with McDowell's many times. I will see what they recommend thank for the reminder
