Vet's are not God and when it comes to digestive issues many make alot of mistakes - see the bloody enema thread, missing the stones when doing a surgery thread, the holly thread where they ran endoscopy, mri, spinal tap, bronscopy, and NEVER DID AND XRAY and the dog had a lead weight in its body for 30 days and died of lead poisoning
Many of us have had dogs with health issues and know what tests are run for certain things and have alot of experience with this breed and also educate ourselves on animal health.
People are human they make mistakes and sometimes it takes a team of people seeing what is going on to give pointers and ideas of what may be going on because they have been through it.
Many vets do not even have dogs so are they with them 24/7 to know things or is it a 15 minute exam and some blood work
How can you prescribe meds when you do not know if there is an infection or parasites?
Go check out the thread on hyperparathyroid/ple/lymphangiectasia - vet said it was hyperparathyroid and IT WAS NOT - I questioned it day one and guess what it was NOT hyperparathyroid it was PLE/LYMPHANGIECTASIA - this dog could have died as PLE is deadly if not treated
check out polina thread where vet said brain tumor - wrong again it was gme and her dog is on right meds doing well and she was going to put her dog to sleep
Everyone can make the call with info given here on what to do with your dog we all have that choice
My motto is don't ask if you do not want info as I personally gather all info here and consult with vet and specialist all posibilities myself - but i will NEVER trust one person for my own health or my dogs health ever again as i have seen WAY too many mistakes
