Just curious as to why a vet would say this? I was told by a well known big time breeder as well...so I want to be 100% sure. I know horses can founder for many reasons....Im just not sure what/if anything the vet was basing this on.
There are good vets and bad vets, and mediocre vets just as with any profession, and the incidence of alcoholism and drug abuse is high among veterinarians. More important than the DVM after their name is their experience and expertise within the specialty (in this case equine repro) in question. I don't take a vet's word at face value any more than I would take anyone else's unless the vet in question is credible...
