I’m sorry to hear about your loss. You might want to check into prophylactic gastropexy, which can be done at the time your pup is spayed/neutered. It is not 100% effective in preventing gastric dilatation/volvulus, but pretty close. More and more military working dogs are getting prophylactic gastropexies to save the government money overall -— or at least that was the case before I retired. Any deep chested breed is at risk, and I lost a Borzoi of my own to GDV.
Good luck with your new puppy!!!
So far so good. Causes of bloat are so poorly understood.
