> I am now incredibly sensitive about the condition a d when my latest gsd showed symptoms we off to the vet immediacy.
Me too! We have had 4 cases of GDV despite my every effort for this NOT to happen. The first was an elderly Basset in his 12th year. He'd been fit and well throughout his life and when this happened (it was very obvious - all the stated symptoms) we got him to our then vet who had to open him up (it had gone to a full torsion). When this happened to our second hound at around the same age, as he'd not been a very fit hound throughout his life after an early gastro-enteritis bug got him when only a puppy, having see how it knocked the stuffing out of the first case, we opted not to have him go through the recovery. My same vet asked if he could open him up to see if he could learn anything. We agreed. He didn't (learn anything new).
Our third and fourth cases happened back in the UK, the third being another elderly male (14 years) and he blew first thing, after his breakfast. Sadly he'd gone by the time we got him to our vet which was done with minimum delay. The fourth was different - an 8 year old healthy and fit male, found in his crate surrounded by froth first thing. No breakfast or prior exercise. We got him to our vet who opened him up, had to remove his ruptured spleen and he was back home by 6 pm that same day, with no further episodes. Interestingly hounds one and two were not directly related. Hounds 3 and 4 were grandfather and grandson. There is some evidence to suggest famial involvement.
When a pup of around 8 week looked as if he was blowing, I had him straight off to my vet - happily he'd gone back down by the time we got there!!
I hope OPs dog is ok.
