Yes, and i have still been unable to find a good vet.
I'm currently going to the 'best' vet in town, but I really don't care for them at all. The first dog I had, had food allergies really really bad, but I didn't want to call it that without a vets opinion. Next time, I'm ignoring the vet and going with my gut instinct. I spoke to 3 different vets at 2 different vet places, and not one would consider a food allergy. It HAD to be fleas even though there was no sign of them, or it was normal (Chewing your tail base bloody is normal? wow...). Both vets wanted to run a full scale allergy test and try about 7 different options. When I asked "Could this be food allergies?" Every vet said "Not likely. Food allergies are rare..." which is where I stopped listening. Food allergies are FAR more common then ever. I could spend $1000's on test or $40 and a non-corn based food. I spent the $40 and all his itching went away.
The same vet when I went in for the first checkup on Nubs, refused to get close to him. Nubs was just laying on the ground getting his tummy rubbed, and the vet wouldn't step an inch near him *rolls eyes*. I've learned if I was going to that vet's office, to ask for the "GSD Guy". One of the vets owns and breeds GSDs and LOVES large dogs. He comes into the room, and just LOVES on Nubs. Loves kisses, does commands with him, and just pets him all over (and while doing the petting, is feeling for anything out of the "normal"). He still isn't the best vet in the world, but I trust him over everyone else in that building.
When you find a really good vet, you'll find you'll drive hours to get your dog to them. I've recently found a vet too late the next town over that many of the rottie and bully breeders use to use that retired last year

Great guy too. All well. When one finds another good bully/big dog vet, they'll let me know. Luckily I don't need a vet visit for 5 more months...
